About this 3D model
This is a simple 2 degree of freedom quadruped using the versatile servo bracket system. http://www.thingiverse.com/thing:5784. Here's a Youtube video of the little bugger. youtube.com/watch?v=Z9ne67bbpSQ. The controller in the picture is a Jaluino http://justanotherlanguage.org/. The servo shield on top is my own design. http://highschoolrobots.com/Jaluinoservoshield.aspx My blog if you are interested.
