Just watch.
In this remix, I added a horizontally mirrored costume, changed the position, and adjusted the code a bit. Aspirus' original project reminded me of "3D paper effect with fisheye" by @l3ccm, and @PutneyCat's excellent remix, so I tried to make a similar (but simpler) remix of this. I didn't look at their code when making it though.
