Dynamo is making good progress. Dynamo is the revamped "Harvest" engine. I have thrown away a lot of the abstractions that were diluting the design simply to accommodate for being able to plug different technologies into the engine (like DirectX vs. OpenGL). Well, that crap is gone now. The designs definitely already seem much more pure and better and conveying the aspect of game engine design.
Now, I just need to go back and revamp the first couple articles up at Managed World to reflect the changes I have made. Perhaps at the same time I can crank out the next article. It's been way too long. Well, a lot of work ahead. I fear I must now get back to it :).
