That's a pretty common request. And it's not that we haven't heard you. It's just a lot more complicated than it sounds. We basically need a new type of material that doesn't replace the existing material. That's the easy part. Making it so the partial material actually knows what parts to replace, what parts to leave alone and where any new new bits are to be connected ... that's probably going to need an ESP mind probe. Who's up for a Poser brain implant?
