Updated gallery

I've just updated the art gallery with a more media-focused layout and new stuff!  The old lightbox-style gallery was neat, but the major issue was not being able to include videos.  Now, new videos have been added, the images are all maximum screen size (no extra mouse clicks), and all text has been moved into mouse hover boxes.  There's only a 5 second window to read the text, but I think you'll be ok.
