It always sounded like a fun project to create a standalone tool to create slideshow movies that used this effect, with full control over where and how much pictures should be zoomed.

One way to get started with an open source community is to write about it. You can contribute to technical documentation, share how you use the software, or write an article for Opensource.com. But getting started writing is easier said than done. The two most common excuses I hear for not writing are: "I have nothing new to say" and "I'm not a good writer."
