>	Tumtum Tree is a robotic pot-plant that seeks "food". The pot actively looks for the brightest light sources in the environment, and then by moving its three legs to appropriate angles, tilts the potplant towards the light sources, thereby maximizing the rate of photosynthesis of the plant. It will get bored and sit down for a while at times. Other possibilities, of course, include ritual dances and pollen dispersion by taking a stroll in the park!
