Re: [Jmol-users] Sync two applet but mouse causes other applet to rotate in opposite sense.

[Jeff H. <jh...@de...>]

Nice, but the effect is not quite right.  If you rotate horizontally, the molecules mirror each other, but when you rotate it vertically the synced molecule rotates the opposite direction so the molecules don't mirror each other any more.  Imagine if you held your hand up to a mirror and moved it back and forth horizontally and the reflection moved with it, but when you moved your hand up the reflection moved down.  Seems kind of weird.
