I've played around a bit with geometric algebra in the past year, and I have to say that by far the best resource (albeit a bit short) was Ben Lynn's implementation in Haskell [0]. Unfortunately there isn't a well-written source that explains the methods well. There are multiple ways to do things, and I had trouble finding elegant solutions to practical problems.
