For tonights HO-HO christmas Hack I was thinking of making some sort
of interactive musical poster with flashing LEDS and music! Does
anyone know where I can get one of those annoying cheap musical
christmas cards? I was thinking we could print out some sort of
Christmas scene, mount it on some expanded polystyrene sheet…I have
shedloads of it at work and then augment the picture with
micro-controlled LEDS and music etc which could then be triggered by a
PIR or something. What do people think??
