If you've ever wanted to remotely access the files on your mac's hard drive through the Safari application on your iPhone (and who hasn't?) then you'll want to download Telekinesis from the genius mind behind Quicksilver. This also allows you to turn your iPhone into a remote control for operating your Mac's iTunes, although given that my computer actually shipped with a remote that I never use as is, the somewhat clunky web-interface for duplicating this function doesn't seem incredibly useful. Suffice it to say that I fully expect this program to get better when it's had more than a week to exist.
Ever wonder how the wildly popular hot sauce got its name? It all started in Si Racha.
