Those are really nifty graphics, Acorn! Popup texts could be a bit bigger, though, as they're hard to read. However, hovering over the eyes, the text overflows a bit (using Chrome).
I like the site, as it is clean, clear and has a nice color scheme. I see something odd with the navbar. It seems like the German and English buttons are mixed up here and there. You might also want to add a favicon.
