I am personally unhappy about the paucity of Cambrian fauna-themed consumer products that are available.

Sweet, sweet Opabinia, everyone's favorite denizen of the Cambrian explosion and a charismatic five-eyed reminder that it's better to be lucky than good. Presented here festooned with heavy-handed metaphorical references to the same general thought as an homage to Stephen Jay Gould's writing on the primacy of contingency over fitness.
