I just posted one in the show off but I just found another one and came up with this idea:
Why not make a topic where people can show real cool photoshop creations they found on the internet?
This is fun to do of course, it's always nice to see good photoshop creations, and besides that you can often learn loads from them.
It's also a very good way to see how creative others are, it helps your own imagination a lot later on. ^^
ONE RULE BTW!!!
Make sure you do not break any copyrights, if sites say they do not want their work shown elsewhere then don't.
Here's 2 I found, one was just posted in the show off.
