Dr. Bones' Undead Architecture

Dr. Bones' has always considered undead to be quite useful; especially considering he is one himself. So he figured, why shouldn't he be able to make a cart out of bones? Or perhaps even a house of flesh? Sure there's the question of "is it morally right to use an infants skull as a doormat?" But those are questions for people who don't see the big picture! Mobile homes! 

When you cast Dr. Bones' Undead Architecture you select from a number of corpses, piles of bones, and so on and use them to make wonderous things, including (but not limited to):

—A skeletal house, with a movement speed of (30ft/40ft/50ft/60ft/70ft), AC of (16/17/18/19/20), HP of (50/75/100/125/150).
—A bridge of flesh, that screams as people walk across it! (It's good for keeping bridge trolls away.)
—A bone trebuchet, with flesh boulders (its not as good as a normal trebuchet, given that it only has about 3/4/5/6/7 uses before it breaks apart, but it comes in handy for those impromptu sieges we all get into.)
—a lamp made of hands! (Need I say more? It turns itself on when you enter the room, talk about convenience! Granted, that's only because the hands are trying to rip you apart, and because of that the light source in the center of them is thusly revealed, but that's only a problem if you're not undead already.)
—A a cart, a wagon, or just the wagon wheel (Not too terribly exciting, but if you ever come across a fellow traveler in need, do help them out by lending them a cart or a spare wheel, would you?)
—A backpack with a hundred eyes (Seriously though, even if the eyes rarely ever catch anything, the fact that there are a hundred eyes staring at them usually deters thief's or pit-pockets.)
—What ever else you can think of!

You can use the 3rd level spell Animate Dead to reassert control over most things you create, but for larger creations (such as a moving house) you might need to up-cast the spell. And the higher level of the spell you cast means the stronger your magical creation will be! Of course, there is no precision to guessing how strong it will be, the quality of your materials, and your skill as a necromancer play the largest role here. Regardless, do be careful around the local clergy—they nearly had a died from a heart attack the last time I visited in my mobile home.
