And this one I'm using myself. Don't worry, I'm sure my story is different than yours.
Here's the springboard. (Grokked from Jay Lake).
It's an article talking about how there is an iPad app which is your Catholic Missal (order of service, over the liturgical calendar). Seems the same priest had already made an iPhone app that was a book of daily prayers. It's pretty interesting. The glow of candles, the dressings of the altar, and the glow from the iPad screen. Heck, it would be perfect for a resurgence of illumination on manuscripts (which, frankly, I love). And the article points out that the current Pope loves his iPod.
Seriously, this gets my creative juices flowing. My story ties into the next novel I want to (re)start (the post-rapture-romantic-comedy), but only through themes, not by actual content (although this kind of app may make an appearance in the novel, it already had an iPhone like device).
And here I'd like to make a shout out to Dan (::waves::) who provided the spring in the diving board I jumped off of. It's good to have smart friends you can joke around with. After about 6 exchanges I went from a vague "That's kinda cool, I'll need to use it sometime" to "Holy Frack, that's such a cool idea for a story." And yes, the donkey will be in it, Dan.
The hint to my story? Here's one of my comments to Dan. "Feeling very 'Canticle for Liebowitz'y about it."
So have at. There's no longer any excuse to not include the Church in your SF.
