Oddly enough, one was just posted on the GetDPI B&S forum just a few hours ago:
I've never heard of a Sphero 60 before either. Thanks for pointing it out, Luke.
Yeah, that's the one I was talking about, I found it interesting and had never seen one before. Get DPI forums are great for Elinchrom Bargains, pity I live across at the Pacific.
I think it'd be an interesting modifier. I'd like to see if you could change the falloff rate and light hitting certain parts of your subject by adjusting the angle of the deflector. Thinking if you aimed it angled towards the roof of the dish you'd get faster fall off down the subject. I wish I lived in Europe, I'd buy it for the hell of testing it out.
