Here's a compact version. The script uses OSX' Quartz to create and manipulate images. Twisted is used to wrap it as a webserver, images are served. More pointers on how to start and use it in the script itself.
You need to avoid using or importing any OSX APIs until after the daemonization has occurred. Unfortunately, twisted executes the entire script file before daemonizing. [that's unfortunate for other reasons besides this, too]
If we are going to change this behavior, we should make twistd do something more correct, and optionally allow it to report startup errors to the console after it's forked, even if those errors don't necessarily crash it during startup. This isn't rocket science, inheriting file descriptors and delaying exit are all pretty easy.
