Microsoft's Garage division of apps has released another one for the iPhone. This one is called Twist, and it's designed to offer a unique spin on online chats with friends.

Microsoft says:

You start a photo conversation with an image that fills half the screen and wait in anticipation to see how your friends will complete the other half. It becomes a storytelling device that can spin off ad infinitum, rather than just capturing fleeting moments."

Photos can come from a person's camera roll or they can search for images via Bing. Users can also put in texts inside the images to give it an Internet meme look. Twist is currently available just in the U.S. and Canada.
