Any ideas/ways to code 2D lighting effects? Like lets say, its a 2d-top-down game, and if I add lights like torches, lamps etc, i would
like it to illuminate part of the map, in a circular fashion. I am also interested in shadows for objects to cast, well sure i could just use the transparency,
but what if I want any object to cast shadows... in real time, based on the sun's position, or light casting. Is it possible in 2d? Also when the character
moves i would like a more "circular" fog-of-war" and not just the square tiles (jaggidly) showing more of the map Smiley.

This article describes how it can be done with OpenGL, and perhaps Orangytang can make an appearance and weigh in on its applicability to Java2D.
