Look into projection theory. a 3d object casts a 2d shadow, so a 4d object would cast a 3d shadow. The implications of that are wild.

Are you referring to the holographic principal?

My dad is a mathematician and loves to play with it. He's got entire notebooks with it but unfortunately nothing profound (he was a professor for years). Mostly just proofs resulting in what's already been published (not sure why, maybe he's looking for something or just thinks it's cool?)
