"Maybe they could be 4 themes from the galleries here....like one could be one terragen, one poser, one fractal, one photography..." - Tresaime Why not? Or to expand on the idea 4 cards that are a combination of the various galleries here. Because after all this is a Renderosity card deck and what better way to respresent it then in the last set of cards . . . Putting a mish-mosh of galleries on the back is also an idea but I think it would be too cluttered. This way by doing it on the front of the twos, you could pair galleries that compliment each other (eg Bryce and Poser)
