• Do not share your private participant key
• You should also upload a readable (and commented) version of your code to help people understand it

Be careful, you will get banned for malicious/harmful and inappropiate content
We analyze the code before publishing the demo, so everything will be safe

How it works

• People submit their projects when the contest is open
• Participants rate other projects using a secret key to prove they are participants
• The person with the highest rating in each category gets the fabulous #1 place
• 1024 pennies (¢) will go to the top project of each category via PayPal. Please donate to keep this competition alive and to pay the winners (this year I have no money :( sorry if I will not pay you)

Fun fact: rate other projects with seriousness or you will end up banned

• Here's the documentation: https://p5js.org/get-started/

Shader demo Download shim

• Write your entry like a shadertoy demo (WebGL1 / GLSL ES 1.0 only)
• 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

No shim

• There is actually no shim here. You start from scratch. (anything is allowed (2D, 3D, canvas, no canvas, etc)
