About
Participants have 15 days to create a cool JavaScript or GLSL program in 1024 bytes or less.
Check out the rules and the existing demos for some cool examples.
Entry is free, so give it a try, it's really fun! >:)
• 1st of July - theme is announced, competition starts, submission form is open
• 15th of July - deadline!!! submission form is closed, you can rate other projects (15 Jul 5:00 PM UTC+00:00)
• 1st of August - no more ratings!
• a few days later - boom, the results are published and winners are announced
Press here if you want to be announced when it starts
Rules
• Your source code mustn't take up more than 1 KiB
• No malicious/harmful code allowed
• You're not allowed to extract personal data from users
• No external files allowed (external scripts and images will be automatically blocked)
• Do not share your private participant key. You will use it to rate other projects
• Upload a readable version (+ comments) of your code to help people understand it (optional)
I will analyze the code before making demos public in order to ascertain if they are safe.
How It Works
• Submit a project when the submission form is open
• Rate other people's projects using a secret key as proof of identity (only participants can rate other projects)
• The person with the highest rating in each category gets the fabled #1 place
Demo Categories & Shim Details
• b = the body element
• c = the 2d context
• d = the document element
• M = a bool that indicates if the user is on mobile
• You only need to submit the script (the setup(), draw() and the other stuff...)
• Check out the documentation: https://p5js.org/get-started/
• Canvas is responsive but its ratio is fixed: 16/9
• Shader inputs: iResolution (w, h), iTime (float), iTimeDelta (float), iFrame (int), iMouse (x, y, clickx, clicky), iDate: float
Note: some chars take more than 1 byte: 2 bytes for chars U+80 to U+7FF, 3 bytes for chars U+800 to U+FFFF, 4 bytes for chars U+FFFF to U+10FFFF, when encoded in UTF-8
