This is amazing and looks really fun! I remember reading a short science fiction story once, "Mimsy Were the Borogoves"[1], where small children were playing with such 4D toys, which were found to be educative in unpredictable ways.

It really makes me want to try it out. I wonder if it's really the same without VR.
