hey, what about a vray t-shirt ? 
Funny you should ask..
Not VRay, but there will be VRay.info t-shirts available shortly.
cool, i will order one !!
super IDEA!
I was asking a long time ago for a t-shirt instead of a CD in 1.1. I really dont see that much use for a CD if the upgrades keep on coming. My opinion would be for a cool Tshirt and a comprehensive manual in the box. maybe son video tutorials by vlado himself.
