David has made all these just for fun. Some of them are a little creepy, but the Photoshop work is really good. One of these days I'll get him to write a commentary for each one, explaining why he changed what he did, and why certain pictures were used. On each page, you can move your mouse over certain areas of the image (usually those with a picture of Stephen!) to see what the original looked like. If you're on a dial-up connection, some of the images may take a while to preload, so be patient.
I'll post more as David comes up with them!
