Yay!! :)
Run and download the newest Blender version, full of cool features like the ones made during Apricot project and Grease Pencil.
I'm happy to see they used my image to illustrate the Grease Pencil feature! It's on the features list. :)
UPDATE: got on Allan Brito's website this demo video of the GLSL and all the game engine goodies. It's good to stress that everything on that video is computed in REAL TIME! :D
