In the aviation world, Heads Up Displays (HUD) are to such a point where they have a plastic-type sheet that can be moved around the cockpit. I was thinking, it would be cool to have a small HUD on the edge of a helmet visor and one of those small RV back-up cameras mounted on the tail...and maybe a ball bearing dispenser, a laser pointer, and an oil-smoke machine. Okay, I'm out of control!
