Stick Men in Peril

The flickr web site has a neat pool of stick figures in peril signs that readers are submitting. (flickr bills itself as the best way to store, search, sort, and share your photos.) These are funny, but they also present an idea for workplace safety and directional signage. Here are a couple of ideas:
Watch Out for Hitting Your Head.
Caution: Slippery Walkways.
Blue Man Falling.
There are 3500 more. Have fun.
