And here's a sped-up vid of the making of this sketch.
Start to finish was about 45 minutes, but I didn't think to hit record until about 8-10 minutes in, next time I'll try to remember to "always record."
Photoshop CS5, cintiq.
The music in the vid is by me. Made in on the iPad using the Korg iMS-20 app and Garageband.
