The iPin is a highly compact laser pointer that can be attached to your smartphone. The laser pointer is compatible with both iPhones and Android phones and comes with a nifty companion app that helps you control presentations.
The iPin simply plugs into your headphone jack and draws power from your phone to function. It doesn't steal too much juice however, only drawing about as much power as a pair of headphones. It comes with a handy clip which can be used to attach it to your headphone cable when you're not using it.
The iPin's companion presentation software gives you touch screen control over your presentations. You can use swipe motions to change slides, or remotely operate a mouse pointer.
