Mine are mostly hung from the ceiling...
I've also got an AT AT on the top shelf.. and a few like the AT-ST worked in with the loose figures. Slave one and two are stuck to the wall down in a corner somewhere.
Lots are in the closet. The Flash Speeder, Naboo Starfighter, Dagobah X-Wing, Hailfire Droid, Droid Tanks, T-16 and more.
And lately I had my fill of the repainted Starfighters - so I stopped buying them. I didn't buy Vader's, Mace's, Saesee Tiin's, Plo Koon's, nor did I buy the recent Hailfire and Droid Tank repaints. When I find the V-Wing I'll pick it up but I'm probably passing on the infiltrator - it just doesn't do anything to me since it looks only a little bigger than the old Infiltrator universal remote control. The only way I'll ever get any of these vehicles that I've been skipping on is if I see them for half price or find them loose for cheap somewhere. Just not spending $20 a piece on repaints anymore unless they're something real good.
