Here's something very interesting. A kinetic sculpture or automata by Kristoffer Myskja (via adafruit via designboom) that conveniently smokes cigarettes so that you don't have to!
the mechanical sculptures of norweigan artist kristoffer myskja are all somewhat strange, but the strangest of all is the ‘smoking machine’, which literally smokes cigarettes. the artwork features a small device made from brass that most prominently features a ramp of cigarettes. each cigarette is gravity fed
onto a holder, where it is lit and slowly smoked by an air valve that is electrically driven. as the gears turn, the cigarette slowly disappears until only the filter is left. the machine then ejects the cigarette and ashes onto the floor below, loading the next one into the holder.
