Elements - experiments in character design

I'm not sure as to the utility of the individual element character cards over at Elements - Experiments in Character Design, but I like a lot of the designs. Here are a few of my favorites, and I warn you that after element 95, they become increasingly boring.

Each card contains a single fact about that element - what it's used for, what it's named after, where it was discovered - not useful but at least trivially entertaining.
