This is an interesting demo of using the HTML5 Canvas and a JavaScript library to draw animated 3d graphics. (This is the 3rd of, so far, 3 posts that Keith has made on the subject.)

Using JavaScript and the HTML5 Canvas element to 'glitch' an image to make it look like it's being played in a broken VCR. Not likely to have much real-world use, but an interesting demo.

Interesting experimental app that uses JavaScript and HTML5 to generate art based on mouse position or finger position for touch devices.

TWITCH by Casey Reas

TWITCH is a series of minimal games within small Chrome windows. How fast can you solve them all? Each game only responds to clicking; mouse position and keyboard are ignored.

These are examples of visual games built using a JavaScript library (Processing.js), rendering into an HTML5 Canvas element.
