Great organization. Easy to read. Maybe you could find pictures of each type? Add those to teh visualization of each type of albinism.

I thought it was really interesting that there were so many types. One that interested me in particular was the partial albinism, or piebaldism. It's so strange that only parts of someone's body could be affected.
