All right, so what is jQTwitter?

jQTwitter allows you to display any user's tweets in a list. You have the ability to set the number of tweets to display as well as the ability to display user's images and set their size.

The list is easy to style with some very basic CSS, as all the elements have their own class.
Each twitter specific links are converted (ie. @ and #).
