Small experiments with the HTML5 canvas-element and javascript. Build from scratch to learn while playing and test javascript’s performance on mobile devices. Landscape is an animated 3D grid with a slowly fading trail, where user interaction creates infinite, always changing compositions. Terrain mapping takes image data from a picture and maps it to a 3D grid. The y-position of the gidpoints are based on color values (r+g+b). In Tiles a small 100×100 square is animated and tiled in the background, user interaction controls color and size of the circles. Patterns emerge when the circles are small enough (moving the mouse up and down).
