Today’s TDC is a fun one!

Draw and shape or explore preset ones and watch/hear it turned into a drum sound. I think that’s what Eigendrum does, it’s as nerdy as one can get with the physics / math of drum shape / sounds.

Of course I drew a cat, and you  can hear what it sounds like by clicking on the cat image here.
