Here's a freebie psd of the widgets I've worked on for fun. These are mainly design exercises that I did for warm-up/cool-down.
Check out the full size and/or download the psd. Hope you guys can get some use from it.
EDIT: Arr! Check out the Drunken Parrot UI Lite (free). It's a UI kit with both HTML and PSD, with the complete Bootstrap components, as well as extra stuff.
