This picture (below) shows the chain lift - lifting a yellow marble. The chain lift picks up and releases about 3 marbles per minute.
Here is a photo showing a couple marbles in motion.
In this picture (below) you can see the "Scales of Justice". The scales are really cool to watch. The scales will tip when the third marble rolls into the side closest in this photo. The other side has several smaller marbles to provide the counter weight so it will reset itself when the other marbles roll out. It tips with 3 marbles but is inconsistent with how many marbles are dumped out. Sometimes only one marble goes, mostly two marbles will dump out, and then sometimes all of them dump.
See the marble collector at the top of the photo.
And as you can see, (below) this sculpture will be going to the law offices of Kam, Ebersbach and Lewis. They are trial lawyers.
