In case it's not obvious (and I guess it's not) the finger-in-air plan is to gut a F-P Activity Centre and install the faders & knobs of a standard cheap-and-nasty DJ rig behind the brightly coloured whizzers and slidey-things. Mind you, since the DJ-culture wave has crested and it's a visual joke that only six people would get, it may or may not be worth the effort.
