Perhaps a better comparison is between Audio tape and CD with VHS and DVD. You'll notice that SACD and DVD-A went nowhere, and mp3s rule the day. The video analogy is of course on-demand or Digital download. They days of removable media are gone and done. Blu-ray was as much a dead fish as HD-DVD.
Tile patterns on middle eastern mosques display a kind of quasicrystalline effect that was unknown in the west until rediscovered by Penrose in the 1970s.
"Quasicrystalline patterns comprise a set of interlocking units whose pattern never repeats, even when extended infinitely in all directions, and possess a special form of symmetry."
It isn't known if the mosque designers understood the math behind the patterns.
