Hudson Hawk (1991)
They find 3 golden crystal type pieces inside DaVinci's works, put them all together, put it in this huge machine which is in a castle. The machine is really old, from DaVinci time. Then the whole thin starts up as the crystal type bits focus energy and basically bits of the machine start spinning around the room both directions.
