Tesseract — the cube of the fourth dimension (3D)

About this app

A 4D cube turns in a chosen plane and is projected into space: in an xw, yw or zw rotation the inner cube seems to turn inside out, although all 32 edges stay equally long in 4D. A true slice with the hyperplane w = c shows what a 3D being would see. Exhibit-ready: also stands on a plinth in "Knowledge as space".
