Ponder the zipper -- and then celebrate its existence with a search on Google.com.
The Swedish-American who thought up and developed the zipper was born on this date in 1880 -- and Google is giving him an HTML 5 homage.

The Google logo is "stitched" on the page and a flick of the mouse unzips it, revealing a pre-populated search result page with as much information on Gideon Sundback as one would need.
Ubiquitous on clothing now, the zipper was first used on footwear and tobacco pouches (really?).
