Update: I was wrong about the whole 'igneous rocks are boring' thing

For years I just saw them as big gray lumps, nothing special. The tip-off was a trip to the Sierra Nevada last fall where a guide pointed out the different minerals in a single granite boulder. He showed me the pink feldspar, the clear quartz, and the black biotite, all telling a story about how the magma cooled. I'd been looking at the rock, not the crystals inside it. Now I can't stop seeing the details. Anyone else have a rock type they used to totally write off?
