If you make a Kickstarter to 4D print them, I would support it for my kids. I think for kids, it's more important to play with real-world physical objects rather than their virtual computer representation.

- js8 9y agoIt's a joke - I don't actually have kids. And I mean the 2nd sentence seriously. Also, quick googling reveals that 4D printers haven't been invented yet, so presumably one would need a KS for those first.
- tomdre 9y agoAs we represent on a 2d paper a projection of a 3d cube, we can print a 3d object that represents a projection of a 4d one. I'm down for the kickstarter.

- gene-h 9y agoGeorge Hart made STL files for 3d projections of a number of 4d objects[0]. Some 3d printers include them as example prints One place I know even used Hart's 3d projection of 120 cell as a standard test print. It has a bunch of thin complicated features that machines have trouble with. One could tell immediately if something was wrong with the machine if the thin pieces were deformed or came out too brittle that normal handling broke them.
