It doesn't have to be world-changing or life-saving to be interesting (though those things certainly don't hurt... usually).
Call me when you find stadiums build on Jesse Silverbergs great principle of MASHers, that save so many lives.
To me it's a shame that this appears publicly posted on a universities site. I suppose that, for this to happen, a Professor must have agreed and supported this paper.. ugh.
P.S.: I do understand very well that simulation of crowds, especially in buildings, is very important but i feel that this is making fun of serious scientists putting real effort into such work.
