Nice one
I dont understand the maths, but I loved the parody of FMA.
Yes you are quite right as well, Ed only loses his arm when he transmutes Al's soul to the suit of armour.
I'd forgotten the old theme tune to the original series as well... have to say though, completely irrelevent anime chat warning... FMA - Brotherhood is MASSIVELY better than the original series.
Anime rant over, good work dude.
