Seth sends this link that is the coolest, most clever, and shocking thing I've seen on the web!! It's a scale model of a hydrogen atom.
It's a relatively simple web page with an electron as a single pixel, a proton as an image 1000 pixels across, and enough pixels between them that, at 72 pixels/inch the web page itself is 11 miles wide!!! That said, at least in Firefox it renders instantly and you can easily scroll to the right where the electron is.
Fascinating!!
