1. No wigs. Hats are okay, and makeup is okay, and I might even go for hair extensions, but I don't feel like putting down the money for a quality wig. (And I don't want to deal with a cheap wig -- someone else can tell the story about how Integra Hellsing suddenly developed short, dark hair because my cheap wig gave up the ghost around lunchtime of Day I of AnimeIowa)
2. Something I can wear to CJAS's cosplay contest. Which means anime or manga character. Maybe video game. Probably not anything from Western fandoms or webcomics.
3. Something that is recognizable as something
* by the mundanes, in case I go out with my work friends, or decide to wear the costume to campus or something. By which, I mean, they might not recognize Kenshin Himura, but the sword and outfit look like 'samurai'.
* Something reasonably specific, not 'what the hell costume is that?'( Current Ideas )
Also, I found this blog post
by Mike Brown that pretty much sums up the whole planet debate. It makes the point that scientists had two classifications: 'round & geologically varied (plus the gas giants, which are round and atmospherically varied with interesting interiors)' versus 'not round and & impact-dominated geology' and 'single objects in distinct orbits' versus 'clouds of similar objects in similar orbits'. Both are useful, and a scientist might deal with one more than the other (a geologist cares more about the first, to the point of even throwing in moons, while a dynamicist the second), and asking 'which is a better classification scheme' is silly, because they are both good and useful things. The IAU wasn't asked that -- they were asked, which classification scheme should be used as planet versus not-a-planet. Which is really a judgment call.
I was thinking the same thing, but this post explains it better. I was thinking about it because I noticed Dr. Bell (Martian geologist) has a 'Save Pluto' bumper sticker pinned to his bulletin board. In retaliation (I assume), Dr. Margot (asteroid and Kuiper Belt dynamicist) put up a 'Save Pallas' sign on his bulletin board. (Guess what both of them think of the IAU's definition? Go on, guess.)
We also have a new official dwarf planet -- Pluto, Ceres and Eris can welcome Makemake (mah-keh-mah-keh) to their numbers. First dwarf planet named after a non-Greco-Roman god, also! (Makemake was the creation deity of Rapa Nui (aka Easter Island) -- Makemake was discovered near Easter, and informally called Easterbunny.)
So, I'm trying to think of a Halloween costume. Here are my criteria, in order from strongest to least strong:
