This an online application for generating cool Twitter backgrounds. Unlike previously reviewed tools (Twitter Patterns, PrettyTweet and Twitbacks) Twilk lets you create background themes from the profile pics of your Twitter followers.

Simply sign in using your Twitter credentials and authenticate Twilk through Twitter oAuth. Once authenticated, a background consisting profile images of your Twitter followers would be created. There are both free and paid options, a free background will have a Twilk badge on it. The badge can be removed for a fixed fee of 5$.
