Portwiture is a site for those who really identify with their Twitter account. Just go to the Portwiture Web site, type in your Twitter username, and see how your tweet profile is represented by photos.
Portwiture works by looking for keywords in your tweets, and then pulling files from Flickr to make a collage. You can click on individual photos to see what made Portwiture pick them.
The Portwiture profile above represents the keywords ‘edge,’ ‘rocks,’ kayaking,’ ‘gallery,’ and ‘design.’
