It's pretty unfortunate that one of the leading videos is by a russian female who doesn't really know what's going on. Asteroids on an oscilloscope is much cooler than her.
Thanks, I had a lot of fun making this. I think it might work better on an analog scope rather than a digital sampling scope. There are a bunch of other interesting videos on there as well.
Tektronix also used to make packaged CRT displays with X Y and Z (intensity) BNC connector inputs.
