I like the idea of recycling materials that have been used at a particular event: that way, even if you didn't attend, you're taking away and wearing a little piece of it!
That's the idea behind a new range of recycled messenger bag designed by Todd Oldham, which incorporate recycled banners from the 2007 Sundance Film Festival which takes place each year in Park City, Utah. Each bag is unique, and based around last year's 'energy passion' film theme. They are available now at $75 on the festival's shopping site. There's also an iPod case made from recycled vinyl banners here for $21. The 2008 Sundance Film Festival runs from January 17-27th.
