I like Bunnie’s pick @ CES (Bunnie is an engineer, worked on Chumby also on the MAKE advisory board. CES is the consumer electronics show in Las Vegas, USA) -

The most stunning thing I saw at CES this year was no gadget, however. It was a mock-up of the “motherglass” substrate that Sharp uses to make its 57″ LCD panels. That is indeed the mother of all glass substrates. There’s these huge frickin machines somewhere out there in this world that takes in that 9 foot piece of glass and deposits thin films of silicon on it, and images microscopic patterns into the films to make all those big, beautiful hi def LCD displays that the gadget freaks lust after. I lust after the machine that makes those panels–eight 57″ LCDs panels at a time. It makes those 12″ wafers at the Intel booth look well…small.
