Easy DIY Lighting Diagrams
But if you, personally, are a personal kind of person, you can use it to demonstrate your lighting prowess (after the fact) for your fellow shooter.
Simply download and open the file in Photoshop, drag and drop the various items (they are still live, in different layers) and flatten that sucker into a jpeg.
Beats illegible scribbles on the back of a cocktail napkin any day.
Thanks to trappedlight for the heads up on the Strobist Flickr discussion group.
