I had an idea a while ago for a bit of fun, and finally got around to making it:

The UK’s current threat level, portrayed by Doomguy.
For those that don’t know, in the classic and mighty first person shooter Doom your health is represented pictorially by an image of the main characters face, as you take damage his face makes it clear. So i wrote some code that scrapes the UK’s current threat level page, takes the current level, and displays the relevant image from one of the following:
Low
An attack is unlikely
Moderate
An attack is possible but not likely
Substantial
An attack is a strong possibility
Severe
An attack is highly likely
Critical
An attack is expected imminently
The Home Office page that displays the threat level is fairly weighty and the scraping code isn’t all that efficient, so it’s fairly slow to load (though does cache the result for 10 mins or so), but considering this is just for fun i doubt i’ll re-write the backend. Sadly considering our current state of affairs it’s fair to say our threat level won’t be changing all that often either.
What i may do, however, is make a nice new frontend for doomguy, in flash, with mouseovers for the other statuses – and animations. I also intend to write one for the American threat level.
