If you can find one (and they're not rare on E-bay), get an HP59306 realy 
actuator. This is a box containing 6 changerover relays controlled by an 
HPIB interaface, the relay contains are wired to 18 4mm terminals 
(binding posts, if that's what you call them) on the back. Assuming you 
have some computer with an HPIB port, you can do computer control of 
lights, small motors, etc  very easily.

2 Thoughts : 

1) Lego Mindstorms :-)

2) _Old_ Fischertechnik. The new stuff is somewhat dumbed-down with too 
many single-function modules, etc, bnt the old stuff from the 1970s and 
1980s is _very_ educational. The only problem is being able to afford all 
you want...
