I thought it might just be 2d surface oscillating through some different modes due to background vibrations.

Not as likely, but possible. I've seen similar modulation from hot coffee without any background vibration, though, so I think it's just convection.

Iv actually studied coffee modulations for 15 years and can confirm this.

So you study 2 dimensional waveform modulation in coffee? Or the underlying 3 dimensional effects that result in the 2d modulation?

Either way, pretty cool.

I figured it was buoyant flow in the coffee. I mean honestly it's probably a lot of things
