Quoting John Conway <conway@Math.Princeton.EDU>:
I don't know. But I once saw it combined in a neat way with one of Escher's infinitely ascending staircases. As one watched a ball bouncing perennially upwards, one heard the ever-rising tone! I'd love to see and hear it again.
I remember seeing that too, but I'm afraid my reply isn't much help. It may have been one of the web sites devoted te Escherology, and it must have been recent (5 years) or I wouldn't have had audio. - hvm ------------------------------------------------- Obtén tu correo en www.correo.unam.mx UNAMonos Comunicándonos
