This is a freebie released by Smashing Magazine that contains a Twitter GUI PSD for the recently released Twitter UI update. It was designed by Jon Darke of Every Interaction and released exclusively for Smashing Magazine and its readers.

This Twitter PSD Template set includes two versions: one for personal accounts and also the new Twitter Enhanced profile page with 835×90 header image for brands and advertisers that you can use for example to make awesome backgrounds or why not take ideas for your presentations. The set is compatible with Adobe Photoshop CS4+.
