Btw, the ZEO head band being hacked with electrodes is said to be a nice gadget, too:

This thing only needs a vibration motor in a wristband or any other signal giver and you have your perfect lucid dream inducer. The material costs are non existent, it only needs a reliable software, which the ZEO apparently has. Let's hope that all the lucid dreaming engineers find together to create the ultimate, low-cost gadget. I somehow think it's a lack of professionalism, not money.
