Enabled ndof devices for controlling colour wheel and cube UI controls

Browse Source 
(eg. colour pickers). Tilting the ndof device up and down and rolling it left and 
right will move the 'colour cursor' in screen x and y, and twisting the ndof device 
will rotate the cursor around the colour wheel (hue). Now you can turn off the 
lights and pretend you have a fancy DI deck!
