Don't have a cow, man.  Like most ooooh!-type stuff, this one seems obvious
once you see how it's done.

Take a vector display.  Substitute a visible light beam for the electron gun.
Mount it horizontally (shooting up).  Spin a helical glass plate over it as
a projection surface.

Wrap a transparent box around it so nobody puts their fingers in the 
Cuisinart.

The spinning helical projection surface effectively allows you to translate
any point (x, y, z) to (x, y, t(x, y, z)), where t is time.

Use three beams for RGB.

Pretty slick.  Now, what I'd like to know (since I've only seen "stills") is
how bad the flicker is...
