Found a fun new site called I Spy. They issue weekly challenges to photographically capture a word. First week was "Beautiful" and this week is "Cold". Fun stuff, sort of a picture scavenger hunt. (If you're looking for a bigger hunt, check out the Monthly Scavenger Hunt at Flickr. This month's included tough words such as Xenophobe, Tryst, Emoticon, Yoke and more (one for each day with the whole month to capture them. All great exercises to expand your photographic vision, and thus, your skills.
