I did a club thing for a bit, every Sat night I rebuilt the inside of the club into a cave, forrest, farm, whatever matched the theme of the event that week. But after the event and i'm finally left to peace, i'll just start building something like a motorbike or something silly like a baloon noose.
Pretty soon I had all this stuff built so I started my own store and now I have plenty of stuff to keep me occupied =)
