Sphere rotating in several directions simultaneously? By rotation I'm here only referring to an object rotating in relation to itself, not in relation to any other object. Also I should add that the axis of rotation should be through the center of the object.
For example with a cylindrical object it's easy to see how it can rotate both around the cylindrical axis and around a diameter axis simultaneously, like this:

But with a sphere I find it harder to visualize several simultaneous rotations.
How many directions can a sphere rotate in simultaneously? How can we visualize different numbers of simultaneous rotations?
Is there a .gif, video, applet or similar that shows several simultaneous rotations of a sphere so that it's easier to visualize it?

A sphere cannot rotate around several axis "simultaneously". Whatever the motion, you can describe it as a rotation around a single axis. (See the Rodrigues'rotation formula.)
