This is for example content in the VR update, so you can dissect it then!
when a globule hits the cookie a decaying signal generator creates the sine movement, and a signal is sent to neighbours to do the same. They all follow a master level, restricted by the two keys(min max)

Something not very visible in the video is the texture on the surface also ‘flows’ from direction of source of ripple - all cookies look towards the source for direction, then the flow speed is tied to speed of cookie (using movement sensor)
