Sphere is a Java Applet for visualising various three dimensional symmetries. I initially wrote it at the same time as my Cubie applet in order to play with lighting effects and work out how to show and control a 3d object. It may help generating ideas for new twisty puzzles, as it shows a sphere with various sets of cuts arranged symmetrically.

Drag the sphere to rotate it.
Drag the coloured sliders left or right to change the depth of a set of cuts. If dragged all the way to the right, the cuts will no longer intersect the sphere.
Click on one of the polyhedra at the bottom right to change the symmetry type of the cuts of that colour.
Click on the area below the bars and a box appears containing the URL you can use to recreate the current pattern.

Here are some examples:
