It's the trans pride flag, drawn and animated with only pen and motion/loop blocks! Thanks to Yeong L for the short YouTube video which inspired this and demonstrated how to make this effect, "flag effect on ms paint": https://scratch.mit.edu/discuss/youtube/tW1BxXOOMDY/ Thanks to @PullJosh and other pen project creators for inspiring me and other Scratchers to make cute little projects like this :P
