This is a song by Jerobeam Fenderson, played through an oscilloscope in X-Y display. This song is specifically made to draw visuals when displayed in x-y, while also sounding semi musical. If you want to reproduce it just connect the left and right audio channels to a scope's X-Y (ch1/ch2) inputs and set it to X-Y. Then play the original track or even this video through it, and you will see the same real time drawings.

For those asking, yes, the N313 cannot display in X-Y by default. You have to modify it by adding a switch to disconnect the internal time base and replace it with the channel 2 input signal. You also have to add circuitry for matching/setting gain and attenuation. Unfortunately I can longer help with how to do that as I no longer have the scope.
