rlm@73: * Intro 
rlm@73: So far, I've made the following senses -- 
rlm@73:  - Vision
rlm@73:  - Hearing
rlm@73:  - Touch
rlm@73:  - Proprioception
rlm@73: 
rlm@73: And one effector: 
rlm@73:  - Movement
rlm@73: 
rlm@73: However, the code so far has only enabled these senses, but has not
rlm@73: actually implemented them.  For example, there is still a lot of work
rlm@73: to be done for vision. I need to be able to create an /eyeball/ in
rlm@73: simulation that can be moved around and see the world from different
rlm@73: angles. I also need to determine weather to use log-polar or cartesian
rlm@73: for the visual input, and I need to determine how/wether to
rlm@73: disceritise the visual input.
rlm@73: 
rlm@73: I also want to be able to visualize both the sensors and the
rlm@104: effectors in pretty pictures. This semi-retarted creature will be my
rlm@73: first attempt at bringing everything together.
rlm@73: 
rlm@73: * The creature's body
rlm@73: 
rlm@73: Still going to do an eve-like body in blender, but due to problems
rlm@104: importing the joints, etc into jMonkeyEngine3, I'm going to do all
rlm@73: the connecting here in clojure code, using the names of the individual
rlm@73: components and trial and error. Later, I'll maybe make some sort of
rlm@73: creature-building modifications to blender that support whatever
rlm@158: discritized senses I'm going to make.
