This is slightly off-topic, but take a look at these two videos on mechanical gastronomy. First one is a lego-machine that opens a bottle of beer. The second one is a Rube Goldberg (homepage, Wikipedia) machine that pours a beer (jump to 2:10 if you want to skip the intro and just watch the action). Rube Goldberg described his cartoons as “symbols of man’s capacity for exerting maximum effort to accomplish minimal results”, but has since given name to complicated machines that perform simple tasks!
