Not sure how does the lens angle change the front/back position of the objects around it. But still; cheaper than a whole space program ;)

- willis936 6y agoI was thinking the meaning of the caption was ray tracing light through the lens from a single point on one side. I suppose you could stick your head in a fishbowl that is sitting on the ground to get the same effect, as long as there are no planes or manned spacecraft directly above you. Technically you can do that with a planar lens if you stick your eyeball onto the lens.
