Working on it now, theres no large SOMA logo so I traced a tiny one and using a large picture of the logo in an awkward perspective to hit the details, should be done later.

Edit: http://www.megaupload.com/?d=XWJCKQCD (Download Link) So I compressed the .ai file so you guys can go into it and edit it if need be. Like I said I could only find small logos so it was kinda hard blowing it up. But if looks like anything is really wrong I'll fix it. Of course it isn't perfect, some edges are a bit square not exactly smooth, but whatever.
Side note: Ever tried contacting them and asking for the logo file?
