"I saw them demoing a prototype at Maker Fair Bay Area this year, and it was truly an amazing thing to watch go.  Glad to see they got funded."

"I'm an interaction designer (by way of graphic design) so I can only speak to my own media here, but I believe the focus on "beauty" in a sketch completely misses the whole point of a sketch: exploration and communication. It also misses the very broad category of things that are not drawings that do the work of a sketch. Granted, my sketches are much more like those Eames sketches above than the gorgeous sketches I see on Core77 regularly, but I've never had someone in my 18 years complain that my sketches weren't pretty enough, just when they're not communicating my idea clearly. The stuff I work on now is also heavily influenced by time, and I've found myself writing almost as much as drawing to try and really convey these activities that are unfolding not just in a (most of the time) 2D interface, but also across time. Writing, along with drawing, is a core design skill."
