OK, now I have fixed a few glitches and my version of the water simulation runs quite well. No Mac dependencies, I am not even using the macpas mode. It should be pretty close to Paul's version. The problem was in the screen update, not the simulation. What is good about this conversion: Small, close to the original, uses OpenGL (so it is fast), isolates user interface stuff (GLUT) into a separate unit so you can change it easily. Mac binary included.

The "continue" keyword seems to work just fine, and is equivalent to "cycle" in the macpas dialect.

I fixed the mouse support, so you can edit the map by clicking, which toggles between water and ground.
