    For those of us who are young enough to remember the old 'colour organ'
    of the 1970's, here it is again. This time it's an LED one, pretty much
    all on a single chip. Now where's the fun in that?

    With today's "music", only one of the three PWM drivers will be
    operational.

    Ho Ho, the doof-doof pwm driver!
    Frank, anyone who remembers the colour organ probably doesn't listen to
    today's "music".

    There are T1 3/4 RGB LES (5mm round) with built in PWM chips that
    constantly cycle through a small set of colours. There is no control
    over the pwm though.

    I can just see the 'ringtone lightshow' on the next wave of mobbly dogs.

    My neighbour's teenagers removed the tweeters and midranges from his
    speakers to enhance their listening pleasure. <shrug>
