Not that I know of, but perhaps TSA's next new million dollar toy to hold us hostage, Sans the new $B facial recognition and boarding pass systems. They are great for teaching magnetism to younguns and looking at lines of force, checking strength, and propagation. I have a couple of them and find they tend to have too much lag and recovery time as demonstrated with the streaking in the Giff, and not all have good resolution but relatively inexpensive. Similar build to an etcha-sketch but laminated. An interesting thing to do is put them on the frame of a monopole motor when on.
