Golden ratio in the design of the iPod
The Apple iPod is the world's most beautiful MP3 player.
One aspect of the design is the basic shape of the device. The rectangle that is the iPod comes closer than any other MP3 player to the golden ratio 1 : 1.618 (also sometimes called the golden section). This ratio appeals to us at an unconscious level.
Attractive human faces have proportions that correspond to the golden ratio, indeed, the human body itself exemplifies this ratio, the Greek Parthenon and many other famous ancient monuments use the ratio throughout their design, the logarithmic spiral on a Nautilus Shell conforms the to golden ratio and even a TV image using those proportion is more appealing (that's why widescreen TV is 16:10). The golden section is deeply ingrained in the design of the Universe. We can't help but be attracted by it.
Here are the ratios of several popular MP3 players:
1 : 1.67 = iPod
1 : 1.75 = iRiver H10
1 : 1.47 = Creative Nomad Zen Xtra
The iRiver is too tall, the Nomad is far too fat, but the iPod's shape, though also slightly too tall, comes closest to this magic ratio. It is certainly no accident that it is the most visually appealing. I am however surprised that no other company has created an MP3 player that exactly uses the golden section (the iRiver H320 comes close by using the same ratio as the iPod, but otherwise looks like an ugly brick - sigh).
So remember, whenever you design anything try to use this golden ratio and people will become instinctively attracted.
