Htmlpatch
Kakariki points us to a giant collaborative geek quilt.
From the site:

The Html Patchwork is an Open Source Embroidery project facilitated by Ele Carpenter, artist in residence at Access Space, Sheffield, July – November 2007. It is a collectively stitched quilt of 216 Hexidecimal colours. Each hexagonal patch is embroidered with the Html colour code, and personalised by the sewer.
