Here is a self-portrait that I took this afternoon. On my right hand is a remote trigger for my camera. A half-press on the button causes my camera to focus on me, while a full press triggers the shot. An Eye-Fi SD card in my camera transmits the image to my Samsung phone in about 3-4 secs, which you can see me holding it up on the other hand.
I took about 20 shots this way without moving from my spot.
