A Few Chime Tags!

All examples include "startspin=on"

startspin="on" spinfps="30" (spinfps="30" forces the animation to look much smoother on most machines)

startspin="on" display3d="ribbons" (ribbons can be substituted with backbone, ball&stick, cartoons, spacefill, sticks, or strands. "wireframe" is the default)
startspin="on" spinX="15" spinY="15" spinZ="0" (spinX, Y, Z dictates the spinning speed of the molecule in degrees per second. This way you can control the spin of your molecule. Experiment - it's the only way to get it right...)
