Stuff like this blows my mind - such simplicity and yet great elegance and feel. Although, as a programmer you are always surrounded by stuff which you feel is amazing and far beyond your capability but you still have an impression that you can still do the same, given you put an equivalent amount of work and passion.

However, designing something like this, seems like an innate ability of very creative people. I find myself far away, imagining something alike and putting it together.
