"You cannot strengthen the weak by weakening the strong. You cannot help the wage-earner by pulling down the wage-payer. You cannot help the poor by destroying the rich. You cannot help men permanently by doing for them what they could and should do for themselves."

This demo shows a particle system creating a smoke effect. This smoke is lit by a partly shadowed spotlight with the smoke aswell as the ground being clearly shadowed accordingly. The shadow from the smoke is also projected to the ground (which is bumpmapped btw). One of my best demos IMHO.

It should run on Radeon 8500, Parhelia and GF3/4.
Source is included as usual.
