my version;

http://bbsrv.imp.leidenuniv.nl/~i400...ter/index.html
(1024x768 pix, complete web-site is cca. 4mb)
same thing but with smaller pix;
http://bbsrv.imp.leidenuniv.nl/~i400...lup/index.html
(640x480 pix, complete site cca. 1.9mb)

obviously, as long as you have some broken pc psus(to take trafo from) and a 50ua meter from somewhere, building this will be very, very cheap and fast...
