I'm unable to run it for some reason :(
The binary gives me this in the terminal:
SIGSEGV MAPERR si_code 1 fault on addr 0x198
Aborted (core dumped)
Well that sucks! Sorry you're running into that. I'm on a laptop with an integrated intel gpu. According to the pict3d docs you could try adding (current-pict3d-legacy? #t) to the top of the file. I am using racket 7.6 'normal' (not CS).
