createVelocity / createTime
Frame-driver + velocity reader — oscillator that tilts in its direction of motion.
Top: createTime() drives a sine-wave x position;createVelocity() on that x rotates the box — tilting in the direction of motion.
Bottom: click Jump to displace the target. The spring glides to it; the live velocity readout shows the derivative.
