In graduate school, I experimented with Arduino's random command to control servo and windshield wiper motors to move in a random direction, for a random duration, at a random speed. However, "random" is not quite the correct word, because I set the upper and lower limits of each category. These prototypes show a few initial studio experiments, some of which turned into full-blown landscape installation art.
<p>A question for you: in the last example can you please share a bit of information on just what the thin, rectangle light were made of, or what name they are sold under, and how did you electrify them? I wish there were a longer set of instructions, but still this interests me, so: BIG Thanks!</p>
<p>In that last piece, what is lighting up, and how is it being lit?</p>
The bulbs are cold cathode fluorescent bulbs, usually used for backlighting LCD screens. They're being lit by a wire from a tesla coil, attached to the end of a swinging cable. As the wire moves around, it comes in contact with the bulbs. Even though it's insulated, this close proximity provides enough electromagnetic radiation to light them up.
<p>Oh, that is cool! </p><p>If you took photos while you built these, you could write step-by-step instructables for them, which I am sure would be very popular.</p>
