Charles & Marie: On Off Coffee Mug

Well, if you want this, you'd best get a move on, since it's only for sale for another twelve hours or so. It's basically a coffee mug that changes color and turns from "Off" to "On" when you pour warm coffee into it.

I'll take a pass, though. And not because of the US$25 price tag. No, it makes no sense to have a coffee turn white from black when you pour black coffee into it. I mean, come on.
