Hi Graham,

The device you pointed to looks like it just shines a laser through a
piece of plastic, that's been designed to make a star pattern, like the
laser pointers that come with lenses for arrows, etc.

The lens (or a simple mirror) could be moved slowly around the room for
the effect they describe.

The other type of laser toys that display spirograph type of patterns
use two spinning mirrors on a couple of DC motors.

There are also displays that bounce a laser of a mirror on a speaker
that changes patterns as music plays.

None of them can be used to display X/Y patterns.
