This is a kaleidoscope on Poincare model of hyperbolic plane. It is made from pentagonal mirrors, which form tiling of the plane. Hyperbolic plane itself moves from left to right. It makes easy to see equivalence of all tiles. Every time you click on the image above, kaleidoscope with new random texture will be shown.
If your browser has no VMRL2.0 plugin , you can see several screen shots of the kaleidoscope.
