O.K, it's a scripting language which wraps up the rather complicated directx library of hardware-independant graphics/3d/sound/etc functions (which you'd normally have to learn c,c++ or pascal to use) into a fun and easy to use language, like a combination of basic and logo. Beginners can acheive results pretty instantly by sticking to the logo-like commands, such as "turn object left 1,90", and move on to using variables and arrays, finally writing their own functions etc, as they learn. It's quite, quite cool.
