This is easily one of the coolest vortexes I've ever seen in my life. I don't know how Rick did it, but he created this super killer 3D snake skin pattern in the glass as it flows down into the depths of the vortex. The colors are really neat together, and the whole marble just POPS when you look at it. Rick was making some of the most interesting marbles and vortexes around during this period back in 2004. Another chance at a sweet piece of marble history here! Signed 'RC 04'.
