Very nice. Can't help wondering how easy that's going to be to shift to mass-production, but still. Cute. Can't help thinking this could be one of those things I bore my kids with tales about having seen the arrival of. Like my Dad and Xerography (although that was anything but boring, of course*...)
Side note: I want to be a boffin. Is there a US university I can buy the qualification from?
*The story goes: he was shown a proof-of-concept style demonstration of the technology, involving a charged plate being selectively uncharged with a projected image, then "dipped" in toner and pressed against paper, which was then heated and shown triumphantly. He described it as looking like lithography, only about a million times less efficient, with no obvious chance of being made practical.
This technology eventually became the ubiquitous photocopier and laser printer, of course. D'oh.
