Got this on eBay lately. I could tell from the pictures it was swirly, but not how good. Back when I was really "into" signals between 1999 and 2004? I got a nice swirly blue prismatic from Keith Brooking. It was fractured, but only $60. I'm a color guy and wanted as many different as I could get so I jumped on it. Later I had Paul Greaves glue it back together for me and it displays good. Anyway, here is a picture of the piece I just got. I was shocked to see just how much color separation it has. There are totally clear areas and deep peacock blue areas. Wow!
Thanks for looking,
