Via the Unofficial Apple Weblog, I came across an interesting / mad (delete as applicable) art installation from the Universitat der Kunste Berlin, which suggests using a cross between a Mac Mini, LCD projector and a limpet mine to liven up journeys on the Berlin Metro:
Parasite is an independant projection-system that can be attached to subways and other trains with suction pads. Using the speed of the train as parameter for the projected content, the projection starts with the train moving inside a tunnel.
It would certainly make the average metro journey a bit more interesting, but I can see one fundamental flaw in trying this on the London Underground – the clearance between the train and the tunnel is a few inches at most. The first installation would likely end in a splintery crunch as the train left the platform…
