This is the Nerd Herd Logo. Well, It's not perfect, but for me it was close enough.
I did create this logo, though I am pretty sure that NBC wouldn't want anyone using this in anything commercial, so please, just use in fan wallpapers or anything for personal use. and please put in a comment what you use this for! Thanks!
The vector file should work on Adobe Illustrator CS thru CS4, if it doesn't, leave a comment and I will see what I can do about fixing it. If you don't have Illustrator, just make the picture above full size for a high resolution PNG.
