When I saw oscilloscope music demos, they amazed and inspired me.
Observing a clever use of interaction between sound and an electron beam is a unique experience.
However, I could not find any beautiful oscilloscope emulators. Lines produced by most emulators barely look like real oscilloscope lines at all.
Because of that I made a cool WebGL demo — woscope, which is a XY mode oscilloscope emulator.
In this post you can learn how to draw these lines in WebGL.
