Cyborg fish?

No, an automated shade for our aquarium. If enough light hits sensors mounted on the front, a stepper motor lowers a window roll shade in front of the aquarium to keep the sun out, and thus keep algae growth down. I built this using an Arduino, the best thing to come along for electronics hobbyists in years.
