Some of the limitations of the LEGO NXT system are related to the fact that, without electronic multiplexers, one can only control three motors with the NXT brick. This individual introduces a mechanical NXT multiplexer that uses two motors but provides 12 outputs!
I have thought about linear designs of this sort, but a rotary design is much more practical. Very nice.
An elegant worm-gear multiplexer submitted to nxtasy.org by Guy Ziv provides another solution in the event that your two outputs do not need to change direction.
