wow this is so cool, i love what you have been doing at the moment, i dont think there are menyworks to discribe but wow...
I say keep it, it looks cool. very bright on the bottom and then the less bright on top and in side. iv got this image that its a glow from a generator or something connected wih the turbine and its this ultra bright glow xD...I think it is alittle too bright. I might have to come up with something a little less intense for the bottom light.
also a cool point to make is to try and get the light to fade in and out.
