Engine Clock

Is it a Clock? Is it an Engine?This is Art! I have created an artifical "Engine Clock" combining different characteristics out of the Engine and Car Theme. The main part of the clock is designed like a speedometer which is showing the current time with an speedometer-like hour and minute hand.On top there is a motorblock with cooling fins and exhaust pipes on both sides. The highlight of this model is a working piston which is moved up and down inside the motor block by the clockworks se
