Pendulux uses an LED inside a swinging brass bob to draw fascinating swirls, stars and spirals on a spinning platter of light-sensitive material.  It’s captivating for toddlers, engaging for grownups, and instructive for all.  Who knew the study of relativity could be such fun?

Pendulux works best in subdued lighting — the darker the room, the more detailed the patterns will appear.  We offer standard models in both table-top and floor-standing designs, and can also create a custom version for your specific needs.  The technology is also adaptable to make paperless chart and drum recorders for applications like seismograph and EKG exhibits.
