By Daniel Waylonis, Google Mac TeamTop Draw is an image generation program just launched in the Google Mac Playground. By using simple text scripts, based on JavaScript, Top Draw can create surprisingly complex and interesting images. Even cooler is that the program has built-in support for installing any image of yours as your desktop image. There's a Viewer application you can install in the menu bar to automatically run with the parameters (such as script and update interval) that you've specified. And there's even a Screen Saver to display the scripts when your computer is taking a break.
The Top Draw scripting language leverages Apple's Quartz and CoreImage rendering engines for graphical muscle. In addition to the drawing commands that are supported by the HTML canvas tag, there is support for particle systems, plasma clouds, random noise, multi-layer compositing and much more.
Because it uses JavaScript in a safe sandbox, you can run any script without fear of malicious action.
Here's the download: http://topdraw.googlecode.com/files/Top%20Draw.zip. Have fun!
Here are some sample images created by Top Draw:
