I don't know if any of you Mac users participated in MyDreamApp, but one of its creators has begun something new over at macheist.com. It's an online adventure game - slash - scavenger hunt of sorts, I guess, with free software awarded along the way, along with discounts on the final mystery bundle of software to be made available for purchase at the end.
The "game" can be played by invitation only. I don't know many Mac users, so I thought I would quickly post this here. Although you'll probably find better and more detailed information about it in the blogosphere, MacHeist can be found over at http://www.macheist.com
Drop me a PM if you'd like an invitation to join the fun, as I've got a few left. I will need a name and an e-mail address. I'll update the thread when they're gone.
