Progress Two Ways
Fun! Exciting! So far so good! Thanks!
I already mentioned that the orange token's icon was going to be replaced with a crescent moon. Here's an image file showing what I'm planning to use for the iconography for the final PennyGems:
Changes: I've added a URL to the white. The droplet on the red has been subtly re-designed. (I didn't like the prototype one; too skinny and a little lopsided.) Orange: obviously, the moon. Black: a much chunkier spiral, which should be a bit easier to count the points on. It also looks more dangerous, although I don't know if that's a good thing or not.
Finally, a closer view of the ninth color. Since the first color, white, has a zero-point shape, it seems unavoidable (at least to us Terry Pratchett fans) to call the ninth color "Octarine" with its eight-pointed cross. I'll probably discuss in a bit more detail why these particular shapes and colors in a later update, but for now, I'll just say that, while I felt that only a cross would do for octarine, I also didn't want any specific cross. I'm rather pleased with the non-specific medieval-ish feel of this one.
