"Insect" that operates on the sun's energy.

The idea with these Beam circuits is that they are powered by the sun. Solar panels gather the sun's rays, convert them to electricity. This electricity is then stored to those black capacitors. When there is enough stored energy, the small motor will start to rotate. In this creation the motor will drive the "insect" along a wire, ruler etc. When the energy storage is depleted, the whole cycle starts again... store -> run -> store -> run...
