If you played video games growing up, or play them now, you might want to check out this fantastic infographic detailing a family tree of video game controllers.
It's interesting to see how the dial-based controllers of the early days evolved into joysticks, and that these then fell from favor until the N64 had that little, but rarely-used joystick on the centre hull. It also seems like controllers from way back when called for more asymmetrical hand positioning.
I also feel that Sony has really nailed it with the PS3 controller. All the buttons are perfectly placed, and it just feels right in your hands.
