Lots of stuff....
I don't have a specific topic for this post. It's sort of an amalgam of many things that I've got going on.
First of all, I finally uploaded the copper pouring videos from last fall to youtube.

And some videos from last spring. The second one is a steam explosion and video evidence of why it's a bad idea to pour molten metal on volatile liquids.

I believe I mentioned I'm taking a computer science class on game design. We haven't started writing games, but we have had assignments that prepare us for using Java and doing game-related things like collision detection. It's all written in Java, so it should work on Windows, Linux, and Apple systems. The assignment linked to below was to create a program that starts with a randomly sized and shaped rectangle moving in a straight line in the window. It is supposed to bounce when it hits an edge. If you click an empty spot, a new random rectangle will be drawn in that spot. If you click a rectangle, that rectangle will be removed from the game. If two rectangles collide, the bigger one will consume the smaller one. (Please note: you may need to have hardware accelerated graphics for this to run. I had trouble on some of my test machines. I apologize if you can't run it.)
