Mock Badge for the 2023 Hackaday Competition (Open Source)

This year, Supercon badges become analog badges! (Or at least pretend to be pretty convincing.) Taking inspiration from the fluorescent oscilloscopes of the past, the 2023 Vectorscope badge is part analog audio playground, part art project, and all about prototyping. Who doesn't love the warm glow and lovely green fluorescence of an old Tektronix tube scope?
