Well, I do now, but even with that knowledge, it doesn’t convey what the OP’s link is. It could, from that description, just as easily be someone with a couple of mallets and, say, an 8-foot long instrument, rather than a staircase hundreds of feet long with a ball rolling down it.
Thanks, twick!
Very cool! Thanks.
