How well do you know your geography? I really suck at it, but I'm getting better by playing these two web browser games:
These SVG games work in modern browsers like Opera 9+ and Firefox 1.5+ and were written by orinoco and published on his Opera blog. I gave him some pointers to get them working in IE+ASV (I updated my guide with these tips too).
He really did some fantastic work - he started with a blank world map on WikiMedia Commons drawn in Inkscape which had all geography stuffed into a single path element and then he broke them out so that each country was its own path, then manually identified them all! It's not an easy task, but it was made easier because the graphics format was an open, well-documented standard in plain text. I hope he continues to experiment with SVG.
Can someone test them in Konqueror and Safari nightlies?
