Asterank has spreadsheet listing asteroids that might be profitable to mine, and a cool interactive view of the solar system and the asteroid belt. In amongst all the asteroids (the little white dots) there are some gold dots floating around. Watch them and you might conclude that they are spaceships on their way to the asteroid belt. Very cool.
Watching the full screen animation, I hear the cooling fan in my laptop kicking on and off every few seconds. I think it must be busy.
