polydimension play online

There are 3d and 4d objects in 3 and more dimensions.
You can see it, scale, rotate with gestures. Solid, transparent and skeleton representations are available. The control is simple and intuitive. There is a tutorial.
Attention! "Unusual four-dimensional" behavior of an object occurs after rotating it in a plane where is a fourth dimension (for example, the x d4 plane)

available objects:
cube 3d
cube 4d (hypercube, tesseract)
octahedron 3d
16-cell 4d
tetrahedron 3d
tetrahedron 4d
icosahedron 3d
snub 24-cell 4d
600-cell 4d
dodecahedron 3d
120-cell 4d

Have fun in all dimensions)
