Angels and Devils

I think this all came about due to the hello kitty type of cute designs you find on purses and t-shirts.
I know it looks nothing like it, but that's where it started.
Maybe I'll turn it into simple flash animations for mobile phones, oops I forgot, I hate mobile phones.
Why are the girls angels and the boys devils?
Well, with the exception of baroness Thatcher, I leave this one to you to figure out.
