While we are busy marking the first Experiment, everyone should take a look around at other peoples work in this and the other groups. There is lots of great work and it is a fun and thought provoking ride through explosions, real-time engines and porosity.
On a personal side note, I saw The Dark Knight at IMAX on the weekend, and it is pretty oppressive in there and we get to see a dark vision of porosity, both in the use of porous space and the impact of explosion as well. Highly, ney HIGHLY recommended!!
