Do a search on the web for a photo screen saver. They allow you to input your own photos - namely Z06's.
Then dig up the best photos you can find and you are done.
Or we can all ask Mrdatalife to work his magic....
PS I put up as many photos of electron blue Z06's as I could find on my website (I was sent three more that I had never seen that I will try to post this week). http://econfloat.tamu.edu/chrisjohnson/vette.htm
