@mwichary The "analogtv" module in XScreenSaver almost does that; it's a circuit-level simulation of NTSC and its various faults, so it's at the "analog logic" layer rather than the "physics" layer.

You can see the effect in action on most of the images posted on the @dnalounge account.
@jwz @mwichary Thanks for pointing this out!
For others who happen across this thread, it's also listed as #XAnalogTV on #XScreenSaver's #screenshots page:

Which, in turn, links to a sample video on #YouTube:
