Wii controller is really 2 halves of a N64 controller

I already know that. Its pretty obvious. Imagine taking the wiimote into your hands - it feels almost like the N64 controller except for the freedom between the two controllers. There's no resticition in terms of movement.

The nunchuck is taken from the N64 joystick and z button design. The wiimote I think is taken from... a remote! It also looks like a hybrid between the D pad and the A and B buttons on the N64 controller.
Never noticed that before, I should've though I've been playing MM and OoT for the past week or so in wating for TP
