There's a lot of programming and coding magic behind SteamOS's
deceptively simple interface, and Valve has done a great job of building an entire operating system specifically for gaming.
That's all fairly inside baseball stuff, obviously, and is fairly
simple; I look at things like Mark Waid's Thrillbent material, which is making some really interesting and
deceptively complex use of a
simple browser
interface to achieve terrifically effective timing effects, and it makes me want to cheer.
