How brilliant is that! A working radio, laid out as a real tube map. I bet the stray capacitance is an absolute swine though.
designer of the original tube map, an engineering draftsman named Harry
Beck, is widely thought to have based the classic London Underground
tube map on electric circuit diagrams. Wiki disagrees, but he was an
engineering draftsman, so must have been at least been heavily influenced
by wiring schematics.
The same designer has also done this. Not quite sure what to make of it: http://www.designboom.com/weblog/cat/16/view/23447/yuri-suzuki-technology-will-save-us-denki-puzzle.html
