Somewhat Nerdy Group Costume?

[Mouse]

My friends and I do a group costume every year, but this year we're stumped for ideas. Our last group costume we were an at symbol (@), octothorpe (#), asterisk (*), and exclamation point. (The original idea was just that we wanted to be punctuation marks, but then we realized it looked like a censored out swear word, so we used neon felt for our costumes and called ourselves "colorful language." Anyway...)
There are four of us, and the only restrictions we have currently are "no clowns," simply because we don't want to be clowns. Any ideas, anyone?

You could be Captain Hammer and his fangirls from Dr. Horrible's Sing-Along Blog. :]

Or a witch from Monty Python, and everyone else be peasants trying to burn you.

Even better, you could be Tim! Everybody else could be knights.

WOW, the colorful language one is genius. Do you mind if I steal that idea for next year?
And perhaps you could be nerdy puns? For example, I was a "Pirate"
Which is like a pirate, but with more pi. :)

And someone else could dress up as someone that's known for being rude and write "third derivative of position"--they'd be a JERK!
Okay, that's all I've got.

Wait, no it isn't. Or, stealing an idea from our school's math department, you could all be in a biker gang called the "Hell's ANGLES". Teehee.

Yeah, you can use it for next year =). Send me pictures!

Me and nearly 30 other kids got together for our first ever Trick-Or-Treat Zombie horde. It was awesome: There were a lot of costumes based off of Left 4 Dead, but we had some really creative costumes: I was the dork dressed up as a contestant on Legends of the Hidden Temple: There's a gold helmet covered in blood spatter in a lot of pictures. XD

pacman and the ghosts. u can use a umbrella with a colorful sheet over it for a ghost, with eyes taped on. and for pacman, make the costume out of a cardboard box.
