[OT] neat display system

[David Paterson <david.paterson@xxxxxxx>]

Somebody posted this at work, and I thought it might appeal to a few
folks here :-

It's a projection display on a "smoke curtain" and it looks
amazing.  If
you've got broadband (or you can download at work) the 22Mb movie is
worth watching.

I'd love to try building one, if I could figure out how he recycles the
smoke.
