I worked on Smoker in the Spring of 2003 for a Digital Video Special Effects class. It is a fluid motion simulator, based mostly on Jos Stam's Stable Fluids method. Here's the old project page: http://swiki.cc.gatech.edu:8080/dvfx2003/118, which may provide some useful information and screenshots, but probably not much. I apologize in advance for the extremely poor acting in the final movie :-)
