for those who have never heard about what is commonly known as
"photoshopping contests" be preprepared to enter a different world..
there are some very big sites with some very talented computer graphic artists which regularly hold contests centering around some theme where people manipulate images or make new satirical images using photoshop (or similar program), often playing off of iconic cultural images.
some of the results are sublime and brilliant, and the creativity can sometimes set you back on your heels.
definitely a good way to waste a day browsing..
anyway, here's a recent one
