Indirect lighting in Blender 2.5-a1

Blender 2.5 Alpha1 that just have been recently released, have gotten a pretty nifty feature called indirect lighting. This is not radiosity, but pretty neat anyway, as you can use all objects and particles as lightsources with colour bleed.

Jason7 from BlenderArtists.org forums have made this demo with Blender 2.5. Alpha1.
