There's plenty of fun things you could do. There are also a few that would be profitable. One that would be very useful, would be to find and bring back down some of the orbiting space junk. And I suppose you could look at ways to make lots of energy and sell it, that had no effect on climate or atmosphere. That shouldn't be terribly difficult, but the tricky part would be to make sure that it worked, without you being there and watching it, but that you retained control of it, so people couldn't simply take what they wanted and never pay you. If you can teleport something bigger &amp; heavier than yourself, you could also bring down a few lumps &amp; bumps from the astroid belt. That would involve doing some tricky things with momentum, like hopping into a close Luna orbit until you had about the direction &amp; speed you wanted... but perhaps if you can break enough laws of nature to teleport, then breaking momentum or thermodynamics wouldn't be a major problem for you... What about causality &amp; consequence? It'd be really nice if you could figure out how to break that one...
