XKCD - big ideas, geeky references, laugh-out-loud humor, and (perfectly) shoddy illustration. I've even covered them here before - twice! Anyway, here's his latest funny-but-plausible concept: a refrigerator which uses conveyor belts to move groceries along their expiration timeline, and eventually into a "BAD" bin. Typical of his attention to technical details, he's thought this out pretty well: the shelves are organized into different spans of time; the door conveyor belt has a functional but space-efficient ramp to dump its expired goods into the same bin as the main shelves; heck, the "BAD" bin even has a handle so it can be removed and emptied over a trash can. We're gradually outsourcing our logistical brainwork to our various devices these days, and this fridge fits right in with that trend. Well done, Mr Munroe - next stop, Kickstarter...?
