Green Flag - Different patterns each time! There is a 1 in 62,510,760 chance that the pattern will be 8 dots moving about the screen. A remix I made with more curves rather than straight lines that I think looks nicer: https://scratch.mit.edu/projects/185509240/ Note that the reflections are in different colours unlike a normal kaleidoscope.
thanks to @Scratch-Minion for the project press space to change thing, I thought black would contrast the colors more than the white.
