So cool!
From the youtube page:
AUDIO
In this part only sine waves (discrete frequencies) were used. Using the harmonic series, i.e. integral multiples of the fundamental frequency, an unlimited variety of sound spectra can be created (additive synthesis). To produce these waveforms the open-source audio programming software Pure Data was used.Which leads here:

Actually, with a bit more software layering, it would be possible to make the audio track more musical. Since for any given X-Y pattern it doesn't matter what frequency the waveform is repeating at, all that matters are the X-Y relative phases of its components.
A while ago I had two sig gens, a HP 8640B and 3325A, set up next to an XY monitor. It's great fun producing very complex patterns with various forms of modulations of the generators. I have another 3325A, but broken. When I get a round tuit, it would be fun to lock the two 3325s together and make some more patterns. But that video blows away such simple play.
OP wont be able to answer as they've been banned.
You know, some people would have continued that sentence a few more words, like "because of ...."
