Apparently it won't work yet! Tragic. In the meantime, I can deliberate on whether or not to call it FOXDIE.
For those with even less of a chemistry background than I have: rust is iron oxide, and pyrite is iron sulfide. It's a good analogy because oxygen and sulfur are in the same group (column) in the periodic table, so they have some chemical similarities.
But that pyrite hasn't been active for a long time.
