HTML5 Canvas Animation with Javascript
summary
Shows how to build working HTML5 canvas animations with plain JavaScript: taps the 2D Drawing API, uses requestAnimationFrame at 60fps, renders a sine-wave particle stream (about 25 balls) and clears the canvas each frame, converts degrees↔radians, computes VX/VY from speed+angle with Math.sin/Math.cos, and layers acceleration onto velocity so objects speed up and loop at screen edges. Live demos are on CodePen demos and include keyboard-controlled acceleration that actually responds.
