System Shock 2 is one of my all-time favorite games, and this custom PC featuring SHODAN is amazing.
Granted, it's not a spot-on SHODAN, but it's close enough to make me more than a little moist and extremely jealous. TTLG forum user TomMer is the creator of this fantastic piece of modding genius, and I now feel totally inadequate about my ability to create anything like this.
Check out the video for a behind-the-scenes look at how this piece was created, and then cry because it's not yours. That's what I'm doing.
