needed seems to be pretty low (in the order of 100V) at anything from 50Hz to
2KHz.
Operable life looks pretty good. Might have to
try and get hold of some of
that for experimentation - I'm not sure where in the UK you can get it though
(the handful of sites I saw were all in the US).
I've got a bunch of the EL cable--it's pretty interesting. On the other hand, there is this rather bizarre

appears to have something to do with stealing a street sign and
hooking it to a Sinclair Z80 system:

Largely gleaned from Hollywood movies, unfortunately ;-)
