Worth1000
This week's site is Worth1000.
Worth1000 (or w1k, as regulars refer to it) is a site that deals with the "photoshopping" (i.e. digital photo editing) of pictures.
While there, you can browse through dozens of contest entries. Contests range from simple tasks like editing a particular picture in any way you'd wish to more difficult tasks like colorizing a black and white photograph to surreal tasks like covering any object with virtual chocolate.
Even if you don't feel like you have the skill to compete, you can still register and vote on the current contest entries. Even more valuable is the Tutorial section, which gives plenty of über-cool advice on how to perform common tasks. Also, for the unskilled, there is a "Training Grounds" section with less difficult tasks.
If Worth1000 was merely a photo editing contest website, it would have been worthy of being Sunday's Site. The quality of most of the entries (and the admission that lousy entries will be tossed out) really allow these contest entries to be breathtaking. Worth1000 goes beyond that, though, by offering a great variety of content for all people.
