Compos are the heart of the event. We will be holding competitions on every aspect of scene related creativity.
Here you can find details about the various competitions that will take place during the event:

• Demo compo
• Combined intro compo
• Game development compo
• Tracked music compo
• Streaming music compo
• Hand drawn graphics compo
• 3D rendered graphics compo
• Wild demo compo
• Fun compos

• Compo entries must not have been released before.
• If there are less than three entries for a compo, the given compo will either be cancelled or combined with another compo. Participating groups or people will be informed before the merging.
• We accept e-mail submissions for the compos. Interested groups or individuals contact the organizers for more information.
• Racism, Child pornography and "optimus humor" (:-P) is prohibited. Submissions will be disqualified respectively.
• We reserve the right to skip long and boring parts in demos during the competitions, such as long boring optimus compatible scrollers (especially when featuring toing toing effect tm) and forever lasting bouncing pixels.
• All shown entries will be spread. Party realease packs will be formed right after the party. Please contact us for on case discussion.
• Rules MAY change! Please don't forget to visit this page for the updated ones.

The demo compo is without doubt the culmination of a demoparty, where groups or individuals compete for the best real-time demonstration. All kinds of demos are welcome, 3D accelerated (OpenGL/Direct3D), Software rendered, Raytraced, anything you like, as long as it complies with the following rules.

Rules

• The demo must be able to run on the compo machine, the composition of which, will be announced in due time but will certainly have pixel shader 2.0 (ARB_fragment_program) capabilities.
• For GNU/Linux demos, the compo machine will be equiped with the latest available proprietary ATI/nVidia OpenGL drivers, XFree86 4.3.0, SDL 1.2, freeglut, libpng, jpeglib, Cg toolkit, and more. If you need any special libraries make sure to tell us about it as early as possible in order to be able to install them on the compo machine.
• For Windows demos, the compo machine will have the latest ATI/nVidia drivers and the latest available DirectX runtime installed. If you need any external libraries please include them with your entry, however the Cg runtime as well as Visual C++ 6/7 (.NET) runtime dlls will be available.
• The entry must be submitted in a zipped archive for windows demos or gzipped/bzipped tar for GNU/Linux before the compo deadline which will be announced in due time. The compressed filesize of the archive must not exceed the 15mb size limit

Have you ever experienced spontaneous human combustion while coding? Then this is THE compo for you!
Burn your last remaining brain cells, code a picobyte intro and be the man of the show.

Rules

• Your executable file must be less than or equal to 65536 bytes. Use of external, non standar libraries (within reason) are also added to the file size.
• The intro must be able to run on the compo machine, see the demo compo rules for details on the compo machine.
• This compo is actually a "combined intro competition". This means that we accept any kind of intros, such as 64k, 4k, 1k and 265b. So in order to do justice to the smaller intros, the file size and the traditional intro category, will be displayed on the big screen prior to the screening.
• For 64k and 4k intros on windows, executable dropping is not allowed, the entry must include the final PE file which will be counted towards the filesize, not a 16bit COM file that generates the PE.
  Executable packers however, as well as tricks to stuff code/data in unused parts of the PE file (or the ELF file for GNU/Linux entries) are allowed.

A new experimental compo for PixelShow this year. Make the best game and win the compo. Any kind of game may participate, from small puzzle games to your new killer first person shooter!

All the entries will be played on the big screen, by their creators if they are present, or by some organizer otherwise, at least 12 to 24 hours before the voting begins. Meanwhile the entries will be available for downloading from a local http/ftp server in the partiplace for everyone to get and evaluate before voting.

Rules

• You must submit a playable executable of the game. It may be a limited "shareware" version in case you want to later comercially publish the "final" game. However, it must be playable and the version that will be shown will also be spread by the organizers freely to the public through the usual means (scene.org, demoscene.gr server, etc).
• The game must be able to run on the compo machine, the composition of which will be announced in due time but will certainly have pixel shader 2.0 (ARB_fragment_program) capabilities.
• For GNU/Linux games, the compo machine will be equiped with the latest available proprietary ATI/nVidia OpenGL drivers, XFree86 4.3.0, SDL 1.2, freeglut, libpng, jpeglib, Cg toolkit, and more. If you need any special libraries make sure to tell us about it as early as possible in order to be able to install them on the compo machine.
• For Windows games, the compo machine will have the latest ATI/nVidia drivers and the latest available DirectX runtime installed. If you need any external libraries please include them with your entry, however the Cg runtime as well as Visual C++ 6/7 (.NET) runtime dlls will be available.
• If you need exotic input devices please bring them with you, otherwise a gamepad and an analog joystick will be available on the compo machine.

There is no size limit imposed, if the entry is too big you should bring it on a suitable medium (cdrom etc), and you may either package your game in an archive (zip/tar) or provide an installer, as you see fit.

The entries will be played on the big screen for a reasonable amount of time (i.e. a few minutes)

Rules

• Every track will be listened for 3:30 minutes, although it can be longer.
• After the end of the compo a mix of 45 seconds from every entry will be available for download, in order to make it easier for you to vote.
• Only one track per artist is allowed.
• Maximum file size is 10mb.
• Allowed file formats are MP3 and OGG Vorbis.
• Every tune should contain the name of the author and the name of the tune. This info must be included within an ID3 tag for the MP3 format, or as comments in the case of the OGG Vorbis format.
• For MP3 tunes, the bitrate must be at 192kbps static. Entries which are not 192kbps or are in variable bitrate will be disqualified.
• For OGG Vorbis tunes, the bitrate must be at 192kbps with quality setting at 6. Any other bitrate will not be accepted.
• Files encoded in MP3 Pro file format will not be accepted.
• The tunes will be played using the latest version of WinAmp.

The "Old School" music compo.
Musicians competing on their skills on the fine art of tracking.

Rules

• Every track will be listened for 3:30 minutes, although it can be longer.
• After the end of the compo a mix of 45 seconds from every entry will be available for download, in order to make it easier for you to vote.

• Each musician can use as many tracks as he wants.
• The tunes will be played using the latest version of ModPlug Tracker and the patterns will be shown at the big screen while the track is played.

Can you draw?
Then this compo is for you! Measure your manhood (or femininity) by drawing a kickass piece of ditigal art.

Rules

• The submitted images must be in one of the following file formats: png, tiff, jpeg. Any other file format will not be accepted.
• The image that will be shown during the compo, i.e. the unsigned one (see below for file submission details) must be in 800x600 true color (24/32bpp).
• Only one image per artist is allowed.
• The picture must be "hand drawn" and not containing rendered nor scanned parts.
• At least 4 stages of the unfinished picture must be included in the submitted archive file (outline, coloring etc).
• The pictures should be submitted in an archive (tar/zip/rar).

The filenames must follow a strict naming convention as to avoid confiusion. This convention is best illustrated by this example of an image named Hydra, drawn by the artist Hercules, using the png file format (for allowed file formats see above):

Hercules_hydra_final.png (final stage, signed)
Hydra_unsigned.png (final unsigned)
hydra_01.png - hydra_04.png (4 intermediate stages)
hydra_outline.png (just the outline)

If you're an expert modeller, or you can setup an awesome 3D scene with the best of them, don't wait any longer, grab the 3D program of your choice, be it lowly or mighty, be it MAX or Maya, Renderman or MentalRay, Radiance or POV-Ray, and get ready to compete in 3 dimensions!

Rules

• The submitted images must be in one of the following file formats: png, tiff, jpeg. Any other file format will not be accepted.
• The image that will be shown during the compo, i.e. the unsigned one (see below for file submission details) must be in 800x600 true color (24/32bpp).
• Only one image per artist is allowed.
• The picture must be entirely computer generated; modifications made after the rendering by hand or any other program will get the picture disqualified.
• The models that are going to be used within your scenes should not be taken from Poser or any website/library, but made by the artist.
• At least 4 screenshots of the process of making the image must be submitted, showing the viewports of the program you are using, or any other part you think may support the authenticity of your entry best, and a screenshot of the final picture in wireframe from within the 3D program.
  In case you use something like pov-ray instead of an interactive graphical program, you must submit 4 stages of the "evolution" of the scene description file.
• The pictures/scene files should be submitted in an archive (tar/zip/rar).

The filenames must follow a strict naming convention as to avoid confiusion. This convention is best illustrated by this example of a 3D rendering named Dragon, created by the artist Smaug in 3D Studio MAX, and saved in the png file format (for allowed file formats see above):

smaug_dragon_final.png (the final rendering signed by the artist)
dragon_unsigned.png (the final rendering unsigned)
dragon.max (the 3dsmax scene file)
dragon_01.png - dragon_04.png (4 intermediate stages)
dragon_wire.png (screen capture of the wireframe scene within the 3d program)

Traditionally the most "relaxed" compo.
Everything is allowed and acceptable here. From "unconventional" demos that you deem inapropriate for the democompo, to 3D animations, or even video recorded with your hand-held camera. Everything goes, no size limit or time limit is imposed. In case your contribution is very large (in file size) you should probably bring it on a CD, in which case, on the label of the CD, you must write the name of the entry, followed by the author's name and a remark stating that the CD is for the Wild compo.

Feeling stupid or athletic? There will be there will be a compo even for you.
From the acclaimed CD throwing compo to the artistic monitor smashing, fun is guranteed! After all, fun is what partying is all about.
