I just love the idea, but if one simply put a little walker in a drum, the drum would probably just turn rather than the walker walk. It would probably take a clever and likely unworkable mechanism to get it to walk without losing height. But, because I like those little walkers and have no memory of owning a paasive one, I think I'll try and make one tonight.
