 * Intro 

 So far, I've made the following senses -- 

  - Vision

  - Hearing

  - Touch

  - Proprioception

 

 And one effector: 

  - Movement

 

 However, the code so far has only enabled these senses, but has not

 actually implemented them.  For example, there is still a lot of work

 to be done for vision. I need to be able to create an /eyeball/ in

 simulation that can be moved around and see the world from different

 angles. I also need to determine weather to use log-polar or cartesian

 for the visual input, and I need to determine how/wether to

 disceritise the visual input.

 

 I also want to be able to visualize both the sensors and the

 effectors in pretty pictures. This semi-retarted creature will be my

 first attempt at bringing everything together.

 

 * The creature's body

 

 Still going to do an eve-like body in blender, but due to problems

 importing the joints, etc into jMonkeyEngine3, I'm going to do all

 the connecting here in clojure code, using the names of the individual

 components and trial and error. Later, I'll maybe make some sort of

 creature-building modifications to blender that support whatever

 discritized senses I'm going to make.
