Well, we are getting near Christmas I guess so we can all expect to see more of this kind of thing in the coming days and weeks. You can watch the video for Jingle Tunes here. I couldn't embed it for some reason.
Jingle Tunes comes from the makers of Looptastic and Sound Warp and uses the same technology as Sound Warp does. So give the video a look if you're in a festive frame of mind.
