Check out Katie’s video about The Unwanted Shape. https://www.youtube.com/watch?v=wN9f-k9oRts

– That’s it.
(If it helps, I made the squares with a side length of 62mm and the triangles 102mm.)

I showed bits from these two old videos:

Big thanks to the roughly one million screaming children who were at some far side of the park I was filming in, but somehow still made their voices heard.

– Let me know if you spot any mistakes!
