my friend martin made a set too: http://www.robotpolishers.com/dhs/

I did a few too ... here.

I love that in the source for the page they have meta keywords like "terrorist safety". hmmm.. ah i think all the terrorists out there are a bit confused.. does this mean safety from terrorists.. or safety for terrorists?? :)

There's a great set of these up at jwz's blog. At least there was a couple of hours ago, livejournal seems mostly hammered at the moment.
