Not a bad analogy. Some computer animation packages let you do just such a thing--manipulate the object in 4D just as a solid modeller lets you in 3D or a paint program does in 2D. It's not quite as grandiose as your conception, but it's a good way to demonstrate one possible fourth dimension. And of course... there is a fifth dimension, beyond those we know. It is... oh, nevermind.
