Kickstarter is full of cool stuff but a project called Altergaze really caught my eye. What it is is a 3D printed platform with a set of up to 3 lenses inside and a holder for your smartphone. The lenses magnify the screen so that it takes up your entire field of view, allowing you to watch video and whatnot in giant, beautiful panoramic views. And the beauty of it is that since it it 3D printed, the firm starting it is making the templates open source and offering partnerships to just about anyone with a 3D printer. They supply the lenses but you get to choose colors and can modify the phone holder to accommodate any kind of phone you want.

The physics comes in with the lenses. The lenses magnify and bend your field of view by refracting light in such a way that makes your phone's screen everything you see.
