If you've always wanted to control something by just thinking about it, but lack the superpowers necessary to make it happen - then you may fulfil your desires instead by reproducing the following project. Using a hacked EEG sensor from a childrens' game, the signals can be measured by the Arduino which then allows a current to flow in various directions across a field of liquid that contains Paramecia. These tiny microbes response to an electromagnetic field in their water, and will swim towards the anode of that field. And thus the mind control via the EEG and the Arduino. You can see this in action during the following video:

If you're new to Arduino, the first step is a solid board for your projects - our Freetronics Eleven - the Arduino-Uno compatible with low-profile USB socket, onboard prototyping space and easy to view LEDs:
