The LED cube!

Inspired by many videos on the internet I have set out on a quest to make my own, It has yet to be finished...

This is one of my first arduino based projects so I am still getting used to all the differences in the code.  The design has been largely copied from 

http://www.instructables.com/id/4x4x4-RGB-LED-Cube/

 however like some of my past projects I plan to program this myself.  It presents many challeges, although the complex tlc5940 ICs have a library in the arduino software there are still little bugs that I cant get around.  Although as I discover more about arduino I hope to solve theses issues such as clock speed; which I know shouldn't be an issue.  From the slightly over exposed picture below you can see all the RGB leds are lit; however all the colums are the same color - there is no multiplexing as yet.
