Given the recent change removing excessive drops, I decided that having a perpetually activated cactus farm was 'unfair' since it tends to have 42 drops constantly in the collection area when the chunks are active. 42/500 is not insignificant. The farm can now be turned on by the flip of a switch which activates pistons to lower blocks that knock off the top of the cacti. Activation isn't nearly as awesome as I was hoping (the sound of 140 cacti dropping isn't as cool as it could be), but if you are are using a laptop and are looking to singe your fingers, flipping the switch appears to spike the processor transiently generating enough heat to make the keys over the processor uncomfortable.
