New Scientist magazine has compiled a pretty darn interesting list of what it says are the top ten weirdest computers ever.
Some are weirder than others, like the chap at the University of Illinois who has developed a method of creating 3D optical waveguides out of photonic crystals, with the aim of making it possible to trap light and even slow it right down and bend it around very sharp corners. The future of optical computing no less.
Or how about DNA computing where DNA has been used to form logic gates and play tic-tac-toe to perfection? My favourite though, has to be the mouldy computing process in Japan where researchers have discovered that slime mould can work out the shortest route through a maze.
