I don't know any projects but the idea is phenomenal; You can actually talk owning these cards (or kittens or any other collectible) because they won't vanish with the disappearance of serves because they will be forever on the blockchain!
Now that cryptokittens has shown the potential, there will be many more applications as such in the future for sure.
How do one get in touch with people who can make this happen? I wanna invest!
That's an excellent question...
