Ok,  Im sorry... but I have to say... that is  Horrifyingly ugly.    
 
   However,  the idea is Brilliant  
 
    
  I think by using some large plexi discs,  and some other material 
possibly like a cut up shade...    One could make a very hot Tron 
gameroom light cover.
 The lampshade just doesnt work well.. partly because its not 
uniform in shape like the tron spinner.  Its also too Deep. 
 Another Idea could be to make a super huge Tron  "Disc"
out of thick plexi.   Maybe a 4ft diamter.    Painted florescent 
color on the outside.   Underlit from the backside.   Blacklights placed 
elsewhere in the room could cause the front side to glow too.
