When I first made this one, I couldn’t get it to fit together so I tried making one that would just be a horse shoe, but while I was creating that version I noticed that I could actually make a loop of it anyway. Not sure what went wrong the first time but good thing I didn’t give up!
I think this is the first perspective illusion I used a cutout to emphasize the solidity of a surface, a technique I immediately applied to some previous figures that needed it.
