They are the basis of the prototype that Bas Ording used to design all the interactions we know today on touch: inertial scrolling with rubber band effect, row of icons for apps, pinch to zoom, etc. It was a fingerwork trackpad with his Director (in 2004!) interactions projected on! It was designed for a Mac tablet, but then the focus shifted to a phone.
