I don't buy the "humanoids are more dynamically stable," argument by Melonee Wise. Humanoids aren't the only thing that can shift their balance... You could also have an arm that swings out a stick with a weight on as a counterbalance. Problem solved, and with much less complexity than a full humanoid robot.
THere might be other good reasons for going with a humanoid design, but there are much easier things to balance.

of this time when I was in college and some friends and I needed a fridge. We ended up getting one for free, through a friend-of-a-friend, but it had a little problem. It had been sitting in a garage for a year or so with food in the freezer part. Maggots had infested it, and then died and dried up in the heat of the garage, so it was covered in little dessicated maggot bodies. Yes, it was as horrible as it sounds.

One of my roommates was going to clean it, but I knew he'd do a crappy job, so I cleaned it out. I hauled out to the back patio, hosed it down, dowsed it with bleach, and started scrubbing. It was a horrible job, but I got that damn thing clean!

I've been getting into blacksmithing in the last few years, and these are interesting. I wish the had some more picture available online.

There are all sorts of old metal goods that are really neat looking. I tend to make roughly finished stuff, but I really like the look of olf highly-finished stuff like tools, knives, and medical equipment.

If anyone is interested, here's a good site for the medical stuff:
