uses 3d trig to move around. the red dot shows where the thing is pointed. use the arrow keys to change the two direction variables, and space to move forward. I might make a game out of this. It might even be like a "knuckleheads 3d" type game. you can use this 3d engine if you give me credit for it. Hope you Love it! It Now lets you change the directions by dragging the direction ball.
