I'm still working on turning a NES zapper and computer monitor into an analog musical instrument.

The circuit generates a VGA signal with just a schmitt-nand trigger and binary counter IC, then gets the X and Y from the light gun as analog voltages by sample-and-holding some sawtooths that sync up to the Hsync and Vsync pulses. These voltages go to voltage controlled oscillators to produce sound. The sound is used to generate the RGB VGA inputs, so the monitor shows sound responsive patterns that feed back into the audio circuits through the light gun.
