BBC Redesign
BBC recently relaunched their portal. Though I find the design lacking in some respects (feels a little one-dimensional, visually), the customization options are implemented well. They are very similar to something our Experience Prototyping group proposed for AOL Dot Com.
One caveat is that it would be nice if the colors updated as you select them and if the options were less prominent. Site done by Fantasy Interactive. (Note: Apparently, this was incorrect information. Still not sure who created the site, but it appears as though it was done internally).
