It's true. An all black screen with no apparent content will indeed be hard to replicate without resorting to the awesomeness that is Flash.
"The Swedish Army has not actually fought a war since 1809"
Well, they're doing something right, then.
Sweden unwittingly executed a great strategic manoeuvre by surrendering all of Finland to Russia in that last war of theirs. That reduced Sweden's land border with Russia to a fraction of what it used to be. Later Finland became independent, which eliminated Sweden's Russian exposure completely. It's easier to maintain peace when you don't share a border with a chronically unstable aggressive empire.
It actually reduced the border with Russia to zero.
No, it didn't. It still had a considarable length of common border with the russian province Finland in Lappland. (To be honest, that was my first reaction too, but as the GP wrote, Sweden stopped to have a border with russia only after Finland became independent in WW1).
I think it's more to the point to say "during WW1". Finland wasn't directly involved.
The present Swedish government recently did a review of the military. The criticism was, more or less, that it was like the British navy before WW I, where officers were promoted based on how clean they kept their ships.
(Lots of money go into the army and lots of equipment is bought -- and these days have almost no units ready. There is talk about changing this a bit.)
I'm not going to claim that Swedish politicians are supernaturally prescient or anything, but... the last time the Swedish military was closed down since it obviously would never be needed, was in the 1920s. I'd better move west. :-)
A very solid game-like web experience. Despite all the talk, it's going to be a while until HTML 5's <video> and <canvas> can deliver something like this.
