Amazing website. The chess prodigy from Searching for Bobb Fisher made the website. His name is Josh Waitzkin. You can click on "guillotine from turtle" for example and see everytime he's done the move in rolling, see every lesson he's taught on the subject, discussions, full rolling sessions where the technique occurs, etc. This is there with thousdands of techniques, and I',m currently watching his passes, as passing the guard is my main focus for 2011.
