Or change the motion curve so that it stays in the recognizable state for longer, like 90% of the time.

I'd suggest capping the animation duration. 90% of 10 hours still leaves an hour for the animation.

If you've got an extended clock (days, months, years, centuries, millennia), morphing could take a while.

Currently the animations all last at most 20 seconds, irrespective of the transition duration.
