This is a video of Youtuber Randomonium discussing, building, and demonstrating his homemade invisibility/distortion shield constructed using sheets of lenticular lens. For those of you unfamiliar with how lenticular lenses work, he provides an explanation and diagram at around 2:30. Randomium estimates the cost of building your own shield to
