I built this portable Harmonograph device which can be carried around in a bag.
The stainless steel gimbals and pivot pins are in-plane design giving much sharper and crisper patterns. Multiple adjustments give the flexibility to change weights and length. My first prototype was made in 1975 and this one is the second version made in 2008. I'm now building the third version and will be up soon. Take a look at this link to see the results;
