Until today, I thought my iPhone's camera had a bug and I was thinking about taking it back in. Pictures that I took had a weird warping effect. It now turns out that it is a "feature" because of the design of the sensor and the fact that the iPhone doesnt use a physical shutter button.
And now you can use this "feature"/"design" to take artistic distorted and psychedelic photos!
Take Distorted and Psychedelic iPhone Photos - Wired How-To Wiki
The reason? The iPhone has no physical shutter and instead uses photon gating on its CMOS sensor. Some parts of the image are recorded before others, much like with a scanner. The iPhone's CMOS scanner seems to be a lot slower than, say, the CMOS sensor on your Canon point and shoot camera. Therefore, as the camera is recording the image, any changes over that small but significant amount of time are recorded.
