Virtual reality glasses for under $30 (the cost of the lenses) if you already have a 7 inch android device. I built this based on a 7 inch tablet mod of the google cardboard design, for smart phones, available on the net. With available VR aps and these goggles you can enter virtual worlds, look up, down, left right, etc. I suggest sitting down first if you view the roller coaster ap, the vertigo is awesome.
