Don’t forget about Professor X!
Sorry to hear you’re having health problems, but if you’re already planning Hallowe’en ideas, you’re in the right frame of mind.
I’m a huge WALL-E fan and love that idea, but you could also go old school and do a Johnny 5. Of course only people old enough to remember “Short Circuit” would get it.
Another idea would be ET. He was kind of built like WALL-E.
Oooh, I have another one; a Rubik’s Cube. Right shape. Instantly recognizable, colorful, and funny. You should be able to construct a cube out of ordinary cardboard that will fit around the chair’s chassis and wheels and have cut out parts on the front and sides so you can see.
For extra realism, take a real Rubik’s Cube, mix it up, and go with that pattern so your costume is an actual solvable pattern (not that anyone would know, or would be able to see the pattern on the bottom, anyway.)
This got me to wondering if anyone makes really ornate wheelchairs for sale. Example, this guy sells custom art-deco/victorian/steampunk computer keyboards, I wonder if there’s someone out there who does something similar for wheelchairs?
I could see me making a varient of The Time Machine.
Timay!
For the truly offensive Halloween costume, wear a Superman outfit and paint your face up like a zombie.
A friend who is in a wheelchair wore a superman costume the first or second Halloween after Christopher Reeve’s accident. It may have been “too soon” as he rankled some people, including one guy who wanted to fight him. When he realized the chair wasn’t just part of the costume, he sorta changed his tune.
Something to make you laugh I hope. I caught an episode of Big Bang Theory the other night. One of the nerds had bought the time machine movie prop. Big kinda steampunky thing with the giant brass levers with massive colored crystals on the ends, the spinning disk on the back with Victorian like decoration, a plush red velvet seat, all sorts of ornate details and so on and so on.
Well, the neighbor girl finally gets tired of all these grown men obsessing over this thing. In frustration she says something like “This is not a time machine. It looks like something Elton John would tool around in the Everglades with!”
So maybe you need to make it Time Machine like but dress like Elton John or Liberachee (sp?).
Are you short? Balding? Unemployed? Living with your mother? A social misfit? Then perhaps a George Castanza (Caaaasssstaaanzzzaaa!) outfit might work out? But then you’d need a Little Rascal I suppose.
On a serious note. We are here pulling for you ya know. Glad to see you have a sense of humor about it. Best of luck.
I saw a young woman in a steampunk-adorned wheelchair at GenCon last year. No idea if she did it herself, or if there’s someone out there who does it.
I’d go for the Professor X costume, if you’re willing to shave your head. OTOH, if you’re already bald, it’s an easy costume. 
You could be our very own Ambivalid for Halloween!
I’m of average hieght (5’10"), on my own, fiendishly handsome, 176 lbs., an uber-geek who has never seen an episode of Seinfeld (where I believe Costanza is a charactor, I’m watching the Robert Taylor Ivanhoe tonight). Anyway, professor X would be a bald guy in a suit, no appeal for me (but I do shave my head).
Boy, I’m really into the parenthetical statements tonight (aren’t I?).
Other fun ideas:
Stephen Hawking
Cutter John (who himself often went all Star-Trekky)
Major Magnus Muldoon
Has anyone suggested Dr. Arliss Loveless from Wild, Wild West? He was way cool and plays into the whole steampunk thing. Also, whatever you decide, will there be pictures posted? : hopes :
God yes, I will post pictures.
I love you all, how could I do less?
This is my vote for as long as you can manage a few steps.
“mien fuher, I can walk!”
If I do say so myself, I do a damn fine Dr. Stranglove voice. I’d have to get my hands on a white wig.
Too late. Post #15 above.
OMG. Can I . . .
Oh, wait, I’m married. Well, it was a nice moment.
Very sorry to hear that.
Davros!
