When is a crazy amazing collab even THAT much better? When BOTH artists use UV glass to highlight the design in fascinating ways, WOOOHOOOO!! This marble would have been legendary without the UV glass, but when you add that, it is simply taken to another realm. Absolutely mind-boggling, no need to say more, the pics will speak for themselves. OK, I will say this - I LOVE how Yoshi gave the flower design a little twist in there, yet somehow the top of it doesn't look twisted. How did he do that???
