That is very cool looking. Although it is listed as a piece of kryptonite. I think it's more one of the crystals. The only kryptonite seen in the movie was a rock. And as for the crystal, a friend of mine and fellow Superman fan has a very realistic looking one. The caption has has for it on his Facbook profile is the "Brando Krypton Crystal". I'll have to ask him where he got it.
