Interesting, all right. Tell me, what kind of pinball machine is that that it yells "tilt" with such a small push? Really, what kind of equiptment needs a tiltmeter that fine? A friend of mine (just finished up at Texas A&M) built a laser. He set up a sand-table and soon had a working inferometer in the bedroom. He could detect a train passing through Bryon, and footsteps on the walkway outside, and trucks driving by, etc. He also set up a target so that a small object (like a hair) placed in the beam would difract the light and you could read the thinkness of the object off the chart. He could measure the thinkness of a hair so well as to distinguish between individuals. The chart was marked in nanometers! He also folded up his brother in the sofabed to see if such a thing was possible. Such is the mind of a scientist.
