Next time you're bored at work you might want to try out this pretty incredible piece of programming which runs NES games via your browser in - wait for it - 3D.
3DNES only runs in Firefox and isn't operating at full speed at present, but as a technical feat it's pretty impressive. It takes original NES games and presents them in 3D - so while the gameplay remains unchanged, objects and environmental features have proper three dimensional properties.
If you're interested in checking it out, head over to the project page.
Thanks to Gonçalo Lopes for the tip!
