Day X+Y Progress

Progress is slow; I have a busy academic life this quarter.  One of my classes is a game class, where the whole quarter is devoted to creating a single game with a group of students.

I'm really glad for that time extension now.  Anyways, today I messed around with some fluid dynamics.   I used some code from here.  I ended up with the ability to add some very fluid looking smoke-like trails.  The goal is to use that to calculate the wind.  This is probably more complicated than necessary (I could just do simple vector calculations), but I really want the player to be able to blow wind through channels and have it intuitively push the balls around.  This enables much deeper gameplay than push-left-or-right.  Plus it looks really nice.  I need to add collision for the smoke, so it wraps around the geometry.
