Critter and Guitari's Video Scope →
“The newly-improved Video Scope re-conceives the lowly oscilloscope as an electrically-colorful visual wonder. Plug in an audio signal, adjust knobs and choose from line, color shift, trapezoid, and random visualizations. (Random adjusts between the other three at an adjustable rate.) It’s all in a pocketable aluminum box with two knobs and a couple of jacks – nothing to clue in anyone that you can make visual marvels with the thing. It’s a magical mystery box. ”
