Yes there have been alot of arguements about which side Midna's eye should be on. Originally, the eye was depicted on the left side (her right side) and the crown-thingy covering the right. But now, on the Wii version of TP, its on the LEFT. It's still left side on the GC and on the official artwork but... I think the true side should be on the right. What side do you think it should be on? Vote vote vote!
This only happend because they had to invert the entire game to ensure that link was right handed for the majority of the players... right? well, anywho, it was originally designed for the cube, and even though the wii version is better, i have to say the eye should be on the left side, as originally intended.
