Try to run this on a computer that has no other windows open, that is practically brand new, otherwise it will probably take 10 minutes to encrypt your picture. I have not got a decrypter, though! Camera relevence soon coming, its just my computer is having a rest. Scratch doesn't have a loop boundary! Sorry guys, this works on some computers, but not on others. It's really just a proof of concept. If it only gives you 13-15 numbers, then you are not alone. My computer does that, but it seems fish8fish's computer doesn't. Press space to take pic.
I've actually been talking with TCFS for ages about this kind of project, but I think I've finally made it.
