Head Diffusion Box: A large sphere you put your head inside and the LEDs emanate from different points to try to diffuse your head shadows
Diffusion Sphere: Use semi translucent paper in one sphere and LEDs outside it, all inside a larger sphere to diffuse it. Light source outside will hopefully minimize shadow. Maybe add fog?
Defocusing Blue: Three white projectors on the walls showing static images (maybe even like, lenses and stencils and a flashlight). There is a rotating band of color filters that makes it monochromatic, but the colors keep swapping. You see the image get less blurry over time then sharply become more blurry, but its just the colors that are changing. [Inspired by Seeing Blue]
Wave propagation: Fill the room with fog and use a projector to visualize light (of large wavelengths that we can’t actually see) propagating, like EM or wifi
Maybe you can electrically charge a dress or something to add motion to something seemingly still
