I fixed my link, got lazy and it bit me.
The reed switch could just trigger something like a simple retriggerable single shot 555 circuit to provide power while moving and kill the effect when you stop.
FWIW, I normally heatshrink the little modules to protect them, that way you can just stick them anywhere. Note that each module has two separate independent LED outputs that are different timing, so you need a module for each two contact points. You also need DC for the module power, the circuit that is sensing movement should supply filtered DC for the circuit.
