Looks nice. Though judging from your photo you seem to be having a very bad day.

Mark,
Nice new look... the graphic on the top is great. Although, as I said over on my blog, I'm not sure what to make of the fact that you've gone away from the standard security "motif" of a black shirt! :-)
Seriously, the site looks great. Kudos on the redesign.
Dan
