Heavy Metal - Green Light
a detail of (pl.wikipedia.org/wiki/Most_im._Edwarda_%C5%9Amig%C5%82ego...) bridge built (rebuilt) in 1948 and renewed (LED illumination was added) in 2009.
How old, good, simple and still reliable meets new, sophisticated and impressive.
And how these two PLAY
perfectly together - creating :
functional and beautiful.
btw - looks a bit like fretboard and headstock of a guitar, doesn't it ? Heavy metal guitar indeed.
