Fascinating thread! Whether it's practical or not - isn't really the point. People spend absurd amounts of money on hobbies, passions, and imagine even clothes and makeup. A quick perusal of the internet reveals many guides, kits, special effect systems....spend the time and educate yourself.
Personally, what a neat skill to acquire and have lots of fun doing it. Does is really matter if it's perfect, no. If you are truly passionate about it or want to create something unique or different go have some fun. Who knows, you may succeed beyond your expectations.
