What he's talking about is the add-on cubes from the pledge manager that we offered. We had some spare bits from our Hegemonic game that are 3D that seemed like they'd fit the game's need for a 3D science token. I believe though that the description in the pledge manager specifically said it would be a set of one of the 5 colors we had and didn't promise any blue. Yep, just looked at the description of the product:
"Want your science to be 3D? We have some extra plastic cubes from our Hegemonic game that would do just great. We'll pack them in a zip lock bag with 25 of the same color. Sorry no color choices, you get what you get."
