Only just found this while researching for a completely different blog post. Love it.
"No Ideas But In Things is a library of controls, animations, layouts, and displays that might be a source of inspiration for interaction designers. Dan Saffer is the curator."
It's a collection of photos of user interfaces from the real world with minimal description. Visual designers like to have lots of examples of graphic design on hand to flip through for inspiration, think of this as a flip-book for interaction designers.
