playing around with a CRT projector

We got to play around with an old CRT projector at Stadtwerkstatt, Linz. It has 3 cathode ray tubes (red, blue, green) and we modified the blue tube's deflecting coil to work in XY-mode.

If working properly, this will be a great option for live performances (we're not entirely there yet), because:
- completely analog projection (deflecting coils are driven with the same signal as the speakers)
- very low latency (much lower than filming an oscilloscope with a camera and projecting it with a digital video projector)
- wide frequency range (more details possible than with laser)
- colors!
- can also be used to play arcade vector games

downsides:
- huge and heavy
- tubes are easy to destroy (by burning in) and replacements hard to get
