Obi ‘smart toy’ projects a laser to drive your pets crazy

A simple laser light is a surefire way to entertain cats (and most dogs), but it gets tiresome for the human operator after a while. As with most thing in life, the old toy has received a modern "smart" update, this one in the form of Obi, a small cylindrical toy that sits on a mantle or shelf and zips a laser around on your behalf. If you want to get in on the action, there's an app to take control.
