Zeitgeist is a studio in Orlando that’s working on all kinds of stuff.  They’re a licensed WiiWare developer, and have recently put out their first DS title.    They’ve also done a few casual Flash titles over the years.  They’re cool guys – I’ve met them at several IGDA meetings.  They’re looking for a few engineers, so head on over to GameJobHunter.com and check out their ads.  They’ve also recently updated their own site – check it out at www.zeitgeistgames.com.
