This one has a need for you to see it in hand, as much as any marble ever had such a need. That's because Shell wrapped the dichro around inside the marble in an infinity loop, and you just can't tell at all how cool that is with out seeing the 3-dimensionality of it in hand. She calls these her infinity loop marbles of course, and they are SOOOO dang cool! You gotta see it! Signed 'Shell 2003'.
