I just noticed this cool new feature on Jason's site. Nick starts a page on GNP and a bunch of seemingly random bug photos pop up. Then I realized that the images were taken in GNP. Maybe not the most useful thing for Nick in this particular case, but I could see how it could be useful in other contexts.
