Ex-Geoworks folks might be interested to know that I bumped into Dave Litwin on SF's Embarcadero today. He works around there; Autodesk has some Maker-y 3D-Printing-ish development at a pier building. There's a TechShop there with some heavy equipment for maker-ing things. It's a good fit for combining his professional interest in programming with his hobby interest in making 3-D puzzles. When he's at home, Dave's teaching his kids to program by writing a text adventure game in Go. He has a Facebook account, but never uses it, let alone posts updates. So if you want to hear what's up with him, you'd better hope that someone chatty bumps into him from time to time.
