Our pals at Gizmodo pointed us to a kit you can buy which turns the plastic case that new iPod Nano's come in into a nice looking speaker kit. Kudos to Bird Electron, the Japanese website selling the kit (sorry, I don't know if they ship overseas, I can't read Japanese) for this hack. Way to reduce landfill and come up with a cool gadget. :)It could be a lack of caffeine making me woozy, but I reckon if you check out the photo on the website selling these babies, the speaker looks a little like a white ORLY owl with big manga eyes. If you're the kind of person who anthropomorphises speakers that is. Not that I'd ever do that. Bird Electron

Windows only: USB thumb drives, memory cards and MP3 players are easy to take with you—and easy to misplace. Portable application iHound aims to make it easy to locate your items and report their theft if they've fallen into the wrong hands. The program places a small "MyPasswords" file that looks like a text document in a device's root folder, and if that file is opened, the iHound website can report the approximate location, IP address, computer name, and more and print a formatted police report. iHound is a free download and free to use after sign-up, although its maker says he may begin charging $1/month for each device starting in February.
