Click the green flag, sit back, enjoy. Please check out the 400+ nice remixes made by other scratchers: https://scratch.mit.edu/studios/27457559/ And of course, feel free to remix yourself!
Completely alienated from "Just 12". This is just a straightforward 'color cycling' animation. I made it to acknowledge "8 block rainbow remix" IS the reigning codegolf champ in this challenge. https://scratch.mit.edu/projects/421038342 Pretenders to the crown were cutting so many corners that the resulting animation became trivial. That's a trail of remixes that is bound to end in 3 blocks: hat block, loop, effect. This project demonstrates such an ending. Nothing to see here, people. Move along. UPDATE: @misteray demonstrated you can make an (apparent) animation with less than 3 blocks of code: https://scratch.mit.edu/projects/427779660/ "Orb" costume created with GIMP. Color gradient, striped and skewed, mapped to polar coordinates, on top of a mirrored duplicate.
