Twilk is a simple site that looks at either your Twitter follower list and/or the list of accounts that you follow, and creates a tiled background image that is then applied to your profile page. The people whose accounts you refer to most often via @ replies, re-tweets, or mentions will show up in the first two columns going down the page.

Although Twilk is primarily a free service, they also offer a paid subscription that will automatically update your background daily.

The idea of Twilk is clever, but it doesn't make for the most visually appealing profile page. It would be nice if Twilk offered to add a screen, or to slightly darken the images uniformly, so that the resulting background didn't look so chaotic. However, if you're looking for a way to pay homage to the folks that you follow (or those that follow you), Twilk isn't a bad way to go.
