here's another photo. the wig is fake, but the doppler effect is still there!

By the way, for those of you wondering, I DID use the following quotes from the show:
"I'll give you a hint: niiioouuuuum"
"I don't care if nobody gets it, I'm still going as the Doppler effect"
I am "The most accurate visualization of a scientific principle"
"It's the apparent change in the frequency of the wave caused by relative motion between the source of the wave and the observer"

P.S. I am going to a "science" college, so most of the students actually got the costume (either after I explained it, or they watch the big bang theory also). Oh, I DID win first prize in the costume contest, and a good number of chocolates from various physics' teachers

That, my friend, is a true nerd. Props to you!

It's definitely American, the culture is quite different. as dan said, the IT Crowd is much more like UK. The biggest difference between US and UK is probably around the comics; it's much more of a niche thing over here. But a geek is a geek is a geek, regardless of where his(/her?) interests lie.
