[sdiy] OT - software XY o-scope

[Toby Paddock]

Howdy,
Are there any free or very cheap software 
o-scopes that do XY? I don't care about 
actually measuring signals, just that it 
should act like a real XY o-scope.
I'm doing some "music to watch on an oscilloscope" 
and I'm looking for a way for people without a 
hardware scope to view it.

My kids and I are making a XY mirror thing to
use with a laser and that got me interested in
o-scope "music" again.

Later,
Toby
