    12 * Intro 

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

    14  - Vision

    15  - Hearing

    16  - Touch

    17  - Proprioception

    18 

    19 And one effector: 

    20  - Movement

    21 

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

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

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

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

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

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

    28 disceritise the visual input.

    29 

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

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

    32 first attempt at bringing everything together.

    33 

    34 * The creature's body

    35 

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

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

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

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

    40 creature-building modifications to blender that support whatever

    41 discritized senses I'm going to make.
