I bought a cast-iron skillet last weekend. Just been playing around with eggs etc with it. It's a lot of fun to cook on. I think it's the culinary equivalent of flying a 747; small adjustments to the engine and wait a while for anything to happen. It is great how it holds heat though, you can pretty much get it hot then cook eggs on it with the burner off.
And also, totally OT, but it is the weekend:
