Here's an idea I've been playing with. I was tempted to enter it in a contest at PanosFX.com, but couldn't since the contest required use of an out of bounds (oob) action and I did this manually. I think the idea is OK, though the execution could stand some refinement.
"For us let it be enough to know ourselves to be in the place where God wants us, and carry on our work, even though it be no more than the work of an ant, infinitesimally small, and with unforeseeable results."
-- Abbé Monchanin
