When I'm bored I go into XenoDream and "create" some kind of wierd thingy, 3d mesh it and import it into a T2 scene, usually a desert. With the amount of Xeno-junk I've thrown into deserts it's amazing the eco-police haven't locked me up and thrown away the key (in some god-forsaken desert, no doubt).
