Okay, so no sign of that Networking History video reappearing on Google Video.

Here’s something else instead: a video showing Multi-Touch Interaction Research.

I particularly like the application for sorting photos; very nice the way photos can be zoomed and shrunk with a simple finger gesture.

There isn’t much information about the type of screen used, but it seems it can handle multiple finger presses simultaneously – I think this is vital for moving such interfaces to the level where they can be genuinely useful (rather than just convenient, as with touchscreen kiosks).
