Make an acrylic cube or a sphere, put inside a projection surface that's able to rotate around one axis. Pump the air out for it to be silent and to be able to use a really thin sheet. Spin it with an external magnetic field. Project the distortion-corrected and spin-synchronized image to it with 2-3 projectors under different angles. Bang, you have your own Star Wars display that's entirely doable by a hobbyist.
