If I can find the pictures, I’ll post the original gravitram later tonight, including a link to youtube where you can watch it in action. Otherwise, maybe I’ll dig up another couple pieces that might be interesting.

For most people, the term would mean a “marble roll” although it is much more than that. The concept is similar in that balls of some sort, in my case acrylic balls, are raised to the top and then allowed to travel through multiple tracks back down.

I’ve had some problems locating the earlier pictures of it, and it requires some set-up to take more since they aren’t much good without a neutral background. I’m still working on taking some more.

Mark, if you want to see the ”original gravitrams” you can google the term. The real first one was installed at OMSI – Oregon Museum of Science and Industry – and it’s still there today. It was done by some guys who worked in the exhibit-building department. It was such a hit that a couple of them left OMSI and started making the things as a business. There are lots of pictures.

I took that original concept, made from welded wire and using ball bearing balls, and decided to ”refine” it, using only natural materials. In my first, the track is all black walnut, and I changed to acrylic balls because the steel bearing balls were simply too heavy and abusive to the wood structure.

I currently have in my shop a second one, much larger. It is simply called Chaos Theory, and it’s made of both wood and other “found objects.” There are sections made from all sorts of things, such as legos, model railroad track, some plumbing pipe and a whole mess of “stuff” salvaged from Goodwill purchases. It is, quite literally, Chaos! However, between other projects and some writing deadlines for a novel and non-fiction book, I simply had to put it on hold. The bad part, other than not being able to work on it, is that it takes up a whole lot of space in the shop. The floor footprint is over 4” x 8” and from floor to ceiling!
