Eventually Xtranormal will be sophisticated, smooth and sweet enough to use for practical marketing purposes. I love their concept, but it's sort of like watching movies on VHS versus say Blue-Ray. Imagine the possibilities, characthers and messages you could send to your potential clients. They already have the ability to you use your own voice for these movies/messages.
You can use Xtranormal for free. It's easy, quick and loads of fun. I like the idea of sending messages to friends & family for jokes, holidays and other events.
Until it's where it needs to be I'm going to continue having a little fun with it.
