This looks like so much fun, and I'm KICKING myself for not having found out about it soon enough to enter. I love fun contests like this, as you can see from my design website on the bottom of my portfolio page! I also have a hard time getting Sammy's Play Doh out without getting very much into it myself.
Core 77 recently challenged their readers to recreate their favorite shoe out of Play-Doh as a tribute to shoe design. Check out the winners on their site!
