Developer Jim Whimpey is riding a bike to cure diabetes, and he's asking for your help (and promising a chance at some great Mac software). For every $10 you donate to his upcoming ride in southern Australia, he'll throw your name in a raffle to win one of two big Mac software bundles, both worth almost $190 each and both including Things, MarsEdit, Tweetie, and Wii Transfer. Any one of those apps is worth the donation, not to mention that your money will go to the Juvenile Diabetes Research Foundation, one of the biggest organizations around committed to fighting type 1 diabetes.
You get a raffle entry for every $10 you donate, so put in $20 and you'll get two entries, and so on. He's asking for all the donations by September 14th, so you've got about two weeks to get over there and put some money in. Great cause and great way to pick up some sweet new apps for your brand new Snow Leopard install to run.
