Click Green Flag, then click one of the arrow keys to see the four different sprites and the patterns they create. The original is Sprite 1. To remix, duplicate that sprite, go into costumes and modify the sprite with Paint Editor tools. Wait until there is an empty centre & press a different arrow key to have a design with more than one pattern.
@heldlaw original instructions: Click the green flag, sit back, enjoy. Please check out the 2200+ nice remixes made by other scratchers: @https://scratch.mit.edu/studios/27457559/ And of course, feel free to remix yourself!
