Yeah, I've mostly ignored it so far as well. I did get Dual Contouring working on 4D signed distance fields, but the resulting meshes are kind of janky. My thoughts are to eventually get boolean operations working on arbitrary tetrahedral meshes and do some CSG, or create a Blender-style 4D mesh editor.

Another game idea is The Incredible Machine in 4D, but it would be so hard to play, and even harder to design the puzzles.
