Here's my thought.
You have a mac. What OS are you running? Does it have iMovie on it?
You are extremely handy with the camera and iMovie can put pics together as a cute little movie. It is really, really easy to do. The boys would probably love it. You can add music and captions, transitions, effects, and voice overs.
The next project, take pictures tons of pictures of the boys working. Then make a movie.
Show it to nasty Den-shelob.
When she asked if the boys did it themselves (which they can easily do), let them say "Yes! And if you want, I can show you how, too." Let them volunteer to do a demo for the pack. There is nothing worse than having a kid show you, an adult, up at computer stuff. Expecially when they're cute.
My evil 2 cents.
