Evolving Content Depending on Day Etc

Is it possible to set up a screensaver that has evolving content that changes depending on things like the day of the week/month/the weather?

In the older version 5, we supported Adobe/Macromedia Flash (SWF) files, which could allow that sort of custom programming. But Flash is dead, so we weren’t able to support it in version 6. I can’t think of any way to accomplish what you want in the current version of iScreensaver, I’m sorry to say.
