I'd seen this before but when my friend, Lori Across Town (formerly Down the Block) sent it to me today I thought maybe some of you Gentle Readers hadn't seen it yet.
As the email said:
This is a holographic projection of a Whale. It is a photographic process that produces images thanks to the differences between 2 laser beams. These images are projected into a gym using a special camera. There is not a drop of water in this room, let alone a whale.
Spooky what science can do, isn't it?
