I have always been fascinated with visualizers of a sound spectrum. A quick google-around will show you all these beautiful liquid shapes that have been generated with sound as input.
I did not find anything available for SketchUp to generate a mesh out of audio, so I decided to create a new extension for that.
Shape generated from an mp3 using this (yet unreleased) extension and then colored by z using @ChrisFullmer his famous color by z extension.
This tool is something I cannot come up with an exact usecase, I made it for fun, not to fill a specific need I or one of my clients had. But at the same time there is so much I can think of one could do with it, going from art to pseudo-random liquid architecture.
What do you think? Is there some usecase this tool could be useful for you?
