The Dot is a Kickstarter project that has finally hit the mainstream. Just snap the Dot onto your iPhone 4/4S and your phone will instantly be able to shot 360 degree video. The video is interactive, letting you swipe across the screen to swivel around. Or you can switch modes and see the full 360 degrees at once in super-widescreen. Normally priced at $39, for a limited time you can get the Dot for only $27.99. You can grab the Dot here.
