I can't help but think this project needs smoke and lasers!

That's cool.
A laser pointed on to one of those fast spinning foil disks would be pretty cool.

Honestly, I think the old ping pong ball floating over the exhaust hose of a vacuum cleaner is more impressive.

Probably a lot cheaper and safer too.

I must admit, I don't think I'd touch that thing while it's on for fear of disintegrating finger bones or vibration induced white-finger.
I thought it was impressive when he visualised the standing waves with dry ice and on the soap film.

This one was linked. It is a technological tour de force... And is projection related....
