Truly omnidirectional omniwheels?

If you move a single omniwheel that way, it might be hard. But when you get them on a robot in a set of three or four, it's relatively simple. Imagine a four-wheeled omni drive set up as a plus sign. Set the wheels along the Y-axis driving one way, and the ones on the X-axis another. The robot should move diagonally (at least as far as I can remember for being up ten minutes >_<)
