Your opportunity to do some good, and join the Founding Troop of Club Thievey, closes out at midnight PT tonight. If you were considering a last-minute charitable donation, Mike's cause is a great option -- plus you get a cuddly lemur.
Speaking of charitable donations that expire at midnight: the OLPC Give One-Get One program closes out tonight. For $400, you can send an XO laptop to a needy child and get another one for your local undersized technology consumer. Sure, it doesn't run Mac OS X, but it will blend in nicely with your old clamshell iBook collection.
