Someone showed me this dragon over the weekend.... if you have a few moments, I highly recommend making one. At the very least, watch the video!

The video is almost creepy. I tried making one but can't make the illusion work. Either I did something wrong or the lighting needs to be perfect.

Oh, the instructions say to look at it with one eye. I'll have to go back and try that.
