As lots of you will know, notch is making a space game called 0x10c 
And I’m wondering if there are any tutorials on how to do the cool lighting and shadow effects like here http://0x10c.com/screenshots/005.png and here http://0x10c.com/screenshots/003.png
Shadows are (usually) done with shadow mapping these days ( http://en.wikipedia.org/wiki/Shadow_mapping ).
Although from the looks of it, that almost looks like shadow volumes / stencil shadows ( http://en.wikipedia.org/wiki/Shadow_volume ). Which seems like an odd choice to me. Or maybe I’m imagining it…
