Do you remember the last time you fully geeked out? You are about to. Universe Sandbox takes the joyous freeplay of Powder and such into 3D. Astronomical scales are laid out for you with a fully zooming and rotatable camera, trails tie knots and stream like ribbons, light waves pulsate at remarkably slow speeds, time is at your command. You can throw a star through the asteroid belt and see what happens. It brings out the awed child in all of us.
