What's the challenge being met by Google with their wavy lines?
It clearly isn't a graphics problem, nor a particularly good synthesis engine being promoted (the page with the application is fun and maybe sound fun, but isn't put forward as the next big thing in audio).
Neither is the graph (in the sense of wiggly line, not ropes and dots) particularly pleasing in some form of to me known theory being applied with graphically or audio-wise special aesthetics, like a critically damped spring system or a perfect way to reflect compressed waves or some something like such ideas.
Probably it is cartoon like doodle making fun of the buzz-word elliptical which has been abused probably since pick-up elements and certain Helmholz integrals have been proclaimed holy as such. No that there is all too much fun in that, or in exchanging sinc functions with fourier integrals, squared energy terms with 1/(1+x) fractions, repeated FFTs with correct impulses and linear systems with systems time varying systems, necessarily.
I suppose (being rather versed in computer graphics and interpolation) the fun is some kind of "curve" suggestion, pointing at the many errors being often made, and how stupid the results are without making people ashamed!
