Both are exemplars of the aesthetic principle of high modernism that perfection of function equals beauty of form. What separates them however is the distance between their moments of manufacture, a space of half a million years.
The iPod represents the future as imagined in my past, from the forties when I read of Dick Tracy's wrist radio and the fifties when I voyaged in space with Dan Dare.
The flint multi purpose tool (axe/knife/saw) from Tchad, whitened by millenia of wind and sand takes me on an opposite flight of the imagination to when it was held and used by a hairier hand than mine.
A third object on my table catches my eye and picking it up I find that my thumb reaches the controlling button at exactly the same point as the thumbgroove of the axe. Although the phone, patinated by a few years of studio use, is not so elegant as the axe, their length is, uncannily, exactly the same.
