Yea, I'm not suggesting it was like "let's start making sweet flames now" or "let's switch over to octopi". They are random swirls, no doubt, chance is most of it with respect to any particular pattern. I was only suggesting that a good glass team could setup their tanks, stream and shear operations to tilt the odds towards producing the kind of marbles they wanted. I doubt Alley wanted his marbles to look like Christensen's or vice versa. Surely, companies tried to distinguish themselves with glass quality and colors too. Isn't that why we can still distinguish many of them today?
