I decided to work on a javascript canvas experiment where I can drag the mouse and scroll within a map. I got a simple "map" drawing colored squares that can be dragged around. I found a perlin noise library, and made the map look like wavy colors. It was pretty slow at that point, so I rewrote the drawing code so it writes directly into the image data. Now I have a smoothly scrolling wavy thing, but I'm not sure what I'm going to use it for.
