So when kids shake the cube, what happens? A typical tilt sensor is going to
go crazy, as will the software. You need a combination of tilt and
rotation sensors to keep the 'virtual cube' stationary in space.
I would suggest testing your sensor filtering and display
algorithms first or you may be quite disappointed with the final result.
And if shaking the unit makes the display go berserk, you can bet that
the kids will shake it vigorously.

Given the effort you are putting into this, it might be worth looking
at using tri color LEDs so that you have something even more colorful
when you're done.
