colorforms are still around - my son has some for maisy the mouse, and dexter's lab. but sadly the manufacturer seems to be saving money by making them from much thinner plastic now, so (a) they barely stick to the background and (b) they tend to curl up into little useless rolls. i'm getting ready to toss them, honestly. sigh... on the space 1999 tip, i remember the most in-demand space 1999 toy when i was a kid was the tracer(tm) gun that actually shot those little disks, shaped like a funky moonbase gun.
