Currently the pathfinding in my game understands which areas are walkable and which ones are blocked based on collision tiles which are drawn on the map in the tile editor (for which I currently use the excellent Tiled). This is great, but it doesn't well handle dynamically placed objects. I took a stab at writing an efficition class to lookup which tiles are blocked taking into account dynamically moving objects. I plan to eventually evolve it into some sort of quadtree-like structure, and dump the tiles in there as well.

I tried to actually hook the space class up to the pathfinder, but didn't have time to actually make it functional yet. Very close!
