Full size it's a bit big, so it's loading in an iframe to scale it down (it's not responsive in that way). Also, there's what I think is a bug in Chrome whereby its blue light doesn't turn off at the end. This chap uses CSS transformations and animations, so won't work in non-supporting browsers. It's fine in Firefox, Opera Next, Safari, IE10+, etc.
I've no idea where the original artwork came from. I found the image that inspired this on my laptop, so must have come across it it ages ago for something, but I've forgotten what.
