In case you missed it, Humble Bundle are running daily over the next fortnight - kicking off at 19:00. Today's selection is a little thin on the ground, perhaps, but that's arguably fair enough considering that it's all about space games. No ground up there, after all.
Specifically, you can pay what you want for X3: Terran Conflict and beat the average for Universe Sandbox - both of which will hoover up an astonishing amount of your time like a rogue black hole. You can alternatively beat £5.97 for Kinectic Void, which is incredibly ambitious despite being in Early Access.
