    1. It happened when I was thinking “Art!“, so that’s what it is.

    1. Sounds like a great project. While you’re working that out, keep the horizon betwixt thee & me…

    2. I did this sort of thing a lot when I was a kid. I’d run an old ignition coil from a train transformer to get arcs in burned-out bulbs.
