"I began to start to think of processes that we can do every day with little effort and a computer would either have to be extensively reprogrammed then taught all the possible combinations of entries. I also wanted something that people could customise to their website — eg: instead of everyone use letters and numbers.
Kittens are the answer to all this. Sure you can teach a computer what a cat looks like, and it will probably have a fair shot at picking kittens from alligators but what about when you put it up against other similarly cute animals? Well... I've yet to have something try and bodge through it."
