Orange/Lemon Julius

When I was younger I use to get Orange Julius often, but I haven't had it in a long time.  When I saw this recipe to make it myself I knew I had to give it a try.  I also made it with Lemon (which is what these pictures are of) both were good, but makes quite a bit so make sure you have someone to share with you!
