This one looks like a really nice gadget for your smartphone:

Very fascinating Roberto! I like visual illusions very much! Could be used for a prediction in a magic trick?

Thanks for the link Roberto! This is really cool! I like having the phone on top of the pyramid (like the helicopter example), as the phone can serve as the "stage" for any magic above the Holho.

The butterfly is nice in the video, and it would be cool to rig up a small floating butterfly with some invisible thread and a tarantula gimmick to animate it.
