1 hour 49 minute full version of Nelson's Computers for Cynics - him talking entertainingly into the camera about computers, how they work (e.g. file systems, filenames), a lot of computing history, inside stories, key people (V Bush, Engelbart, Kay, Gates, Jobs etc), lost opportunities etc. Pretty funny, like his term the PUI (PARC UI).
His Geeks Bearing Gifts is a more detailed, written treatment of the same material: http://www.lulu.com/shop/ted-nelson/geeks-bearing-gifts/pape... . It's also a more affordable alternative to Computer Lib/Dream Machines if you want to send him some money.
