Motion Amplifiers: Sketching Dynamic Illustrations Using the Principles of 2D Animation
summary
A sketching application called Squid exposes a toolbox of motion amplifiers that implement concrete 2D animation principles (anticipation, staging, drag, slow in/out, squash-and-stretch) by deforming an underlying grid which updates strokes in real time. Effects are composable and controlled with strength sliders and interactive motion profiles, it operates on pure geometry (no skeleton), and user tests show novices rapidly produce expressive animated illustrations without a timeline.
