One trick I've noticed to make animations/transitions "snappier" and more natural is to use quadratic/square (power of 2) scaling. For fun I did it on this clock just saving it locally - you can do it by modifying line 140 of `bezier_clock.pde` to square the ratio instead of simply assign it:

    animationRatio = ratio * ratio;  // can also replace with sqrt(ratio)

Again, just makes it a little bit 'snappier' (remember you have to hit spacebar to turn on continual animation), and scales it so you can determine the numbers a bit more clear earlier in the cycle because of the scaling on (0.0, 1.0]. This is certainly a fun piece of code to play with.
