So I have combined my fascination with space and asteroids into a vertical scrolling game of "dodge that rock or die!".
Actually, I first started this as a little Torque2D side project years ago, called "HotWired" it was pretty basic and had quite primitive dynamics. Quite some time later I built an HTML5 analogue to that game (some day I'll upload it, but it's _very_ primitive).
I switched to straight-up Java and OpenGL, and had great fun learning about stencil buffers and fragment vs vertex shaders.
