This interesting and nicely designed little site traces the attempts by twentieth century composers to escape the bounds of traditional staff notation and devise more graphical means of presenting their avant garde scores. The results of their endeavours are presented in a series of zoomable scanned images which are accompanied by interviews and sound clips. They're all very idiosyncratic, and regardless of how effective they were at conveying musical ideas, some of them are quite visually appealing... Its just a pity none of them are available as wallpaper-sized jpgs. (via Metafilter)
