Giles Colborne's presentation discusses strategies for simplifying designs. It identifies two new rules for simplicity.
It also looks at why simplicity has become so important in interaction design, whether simplicity and usability are the same thing and exposes some myths about simplicity.
It's a version of a highly-rated talk from the Usability Professionals' Association (UPA) conference in Portland in June 2009.
I've added some 'Post-It' notes so it all makes sense!
UPDATED 18 June 2009: Fixed some of the builds and fonts to improve the appearance.
