I went to visit a friend last night and as were just sitting around chatting, I look down and see this beautiful, but unnerving large green spider sitting on my arm. We captured it in a bottle and then let it go back outside, but I wanted to find out just what kind it was, so spent this morning looking it up on the Internet. Turns out it was a harmless spider (to humans of course) called the Green Lynx Spider. Here's a picture (not of ours, from another site).
