+* A Flower
+
+A flower is a basic creature that tries to maximize the amount of
+light that it sees. It can have one or more eyes, with one eye being
+"special" in that it is this eye which must recieve maximum light. It
+can have multiple articulated joints and mulcles.
+
+Want an algorithm that uses the sense data of =vision=
+=proprioception=, and =movement= to maximum benefit in order to look
+at the light source.
+
+The light source will move from place to place and the flower will
+have to follow it. 
+
+The algorithm should be generalize to any number of eyes and muscles,
+and should become /more/ preformant the more sensory data is
+available.
+
+I will punt on working out an elegant model of motivation for the
+flower which makes it want to go to the light.
+
+Maybe I need a motivationless entity first, which just learns how its
+own body works? But then, wouldn't that just be a motivation itself?
