I created a generator file to come up with "cyberpunkish" corporation names (specifically to play Shadowrun, but these aren't Shadowrun-specific). It will occasionally create silly names, and it will at times create the names of real companies, but generally it does a good job in creating suitably high-tech corporations for you. Hope people find this useful!
The link to the .ipt file is here
Also, I would like to submit this one for the NBOS site as well (my name is Chris Clouser).
