Would be way more interesting to do again today and track with GPS. That way you can see all it’s travels and not just its ending point.
I wonder if anyone’s tried that, it’s a good idea. A couple summers ago at the local ArtPrize, one of the exhibits was a dynamic piece of alleged art that took its cues for sound and movement from the signal of a US buoy that became unmoored and is floating somewhere in the Pacific (it antedates GPS). With GPS tracking, the number needed could also be greatly reduced.
