Reply to Yet another DIY RGB grid controller

greetings fellows!
I would like to thank you for such a great community and community! A lot of interesting and inspiring things going on around here, so I've decided to share with you some of my own projects.



After all this fuzz about the new Kontrol F1 I thought some one might find my project interesting. The project started as an RGB monome clone( a 8x8 grid of colorful buttons ) but could be used with anything that supports midi so I tried it out in Traktor and here are my results!
The idea was to test/demonstrate the use of different colors on my device and see whether it was possible to fully operate Traktor with just one grid controller and I believe I covered most of the major controls.

here is a little demonstration video of it in action:
and more details how it is mapped: http://tomashg.com/?p=576

what do you believe about this? any suggestion or ideas how it could be used best or any cool tips/tricks with the mappings?
