I like it when smart people show their projects :)

IEEE Spectrum also showed this picker-upper robot which is also cable driven:

Maybe these items were inspired by those wacky cams on wires used at football games ?

I doubt whether I'd ever try building one of these but I think Mural V2 is a really cool project.
