A tesseract morphing into a runcinated tesseract and then revolving it in 4-D.
I wanted to give an idea of what the runcination operation looks like in 4 dimensions. Basically, the 8 cubes of the tesseract are pulled apart and filled in with more cubes and triangular prisms to create the runcinated tesseract.
The colors show where the cubic faces are in relation to one another: +X (red), -X (cyan), +Y (green), -Y (magenta), +Z (blue), -Z (yellow), +W (white), and -W (black).
