This is a new chain with the Aphex Twin logo. New version 1.1 can be added as a new item rather than a replacement, although it's a bit more work. For anyone who doesn't know, Aphex Twin is a well known electronic music. Come To Daddy!
You'll need IMGTool 2.0 to replace a chain, and the San Andreas GXT Editor v1.2 if you want to add it without replacing anything.
It is a replacement for the dollar symbol chain, although I think it can replace any chain with a medallion thingy on it. For those who don't know, Aphex Twin is an electronic musician with a cool logo.
New Version 1.1 Now you can add this as a new item at the store of your choice, although it's a bit long process. I also used a better model for the logo. This one is much better and is properly round.
