Take the "Fake or Photo" challenge!

So, you think you can tell the difference between a 3d rendered image and a photograph? Prove it by taking the "Fake or Photo" challenge! This link http://www.autodesk.com/eng/etc/fake_or_foto/index.html will take you to a grid of ten images. Test your visual prowess by choosing if the image is a rendered piece of 3d graphics or an actual photograph. You can click the thumbnails for a larger version to make deciding a little easier. I got all of them right PLUS the bonus questions at the end...score! (Although to be fair, since I have been staring at 3d rendered images since around 1990, I might have a slight advantage!) So have some fun, take the challenge, and post your results for the world to see!
