It’s bit late and off-topic, but anyway, if you haven’t seen it yet… here is a cool use for your oscilloscope: use it as a display for a demo. This demo won the third place in Assembly Summer ’07 shortfilm competition. I really like those sine waves. By the way, the guy who made this is 15 years old. The oscilloscope is connected to PC soundcard and is in X/Y-mode, with right channel connected to X and left to Y input. Download its waveform from here to see it on your oscilloscope!
