The Green Man Private Reserve
This year I'm bringing a case of "The Green Man Private Reserve" vineyards with samples of the four different varietals: Cabernet Sauvignon, Chardonnay, Sauvignon Blanc and Merlot. The label is designed on the logo from the 2007 theme. I would have preferred to alter the image so that it contained a wine goblet or grapes but I ran out of time.
Intelligent image resizing
Dr Ariel Shamir has come up with a way to resize an image while still retaining the important content. The demo on intelligently erasing content is perfect for people who want to crop their x-girlfriends out of their pictures.
UPDATE: HackZine has an article on some related technology.
