Hasbro has come up with a $35 plastic viewer you attach to your iPhone or iPod Touch (it kind of looks like those View-Master viewers still sold by rival Mattel) that presents gaming, tour and other applications in a 360-degree 3D viewing environment. The toy company has also released a series of apps for the "MY 3D" device, some free for now, including "My3D Presents," a movie trailer app, "Sector 17," a first person shooter and 3D maze app "Bubble Bolt" which you navigate by tilting the phone in the right direction. Target and Target.com has exclusive rights to sell the MY 3D viewer until June.
