That's why I am digging ivoteforart.com. Artists (or yourself) post their works and you get to vote for them to promote them to the front page. The works are also for sale, so if you find something shiney, you can buy it. The art I've been seeing on there is hip, modern, and way cool. Great for inspiration or 5 minutes worth of distraction.
So there's your really cool website for the day. Enjoy!
