Since the goal is to create an illusion of real physics, I wonder when they'll just cut to the chase and start using actual physics engines. Reason I mention it is neither this nor bezier curves deal with the target changing mid-animation very well. CSS just starts over from the current position, which breaks the illusion. A physics engine would maintain the illusion, and could be simpler to specify: transition: physics(system=gravity, force=10, bounce=on, dampening=3) transition: physics(system=spring, force=5, bounce=off, dampening=5)
