Macheist to get it! ShoveBox, WriteRoom, Twitterrific, TinyGrab, Hordes of Orcs are free. Mariner Write will get unlocked after 50,000 download the free software. Some good apps for those budding writers. The catch? You might get addicted as Macheist has been known to have some great puzzles for more free apps as the year progresses. It usually ends in a bundle that you pay for... BUT not this one! So, if you have a mac or know someone who has one, this is a great deal to try some software they may not have otherwise. Go, have fun!
Edit: Now get VirusBarrier for free too when you announce it on your Facebook account. Not bad. That's a $70 value.
And just so you know, I've been doing the MacHeist thing for a couple of years now and it really is a good bargain for mac users. Also great fun trying to solve puzzles.
