I came across this train schematic a number of years ago and I credit it for sparking my interest in blue prints, schematics, medical illustrations and the like. Its original non-monochromatic format was the featured piece of artwork on my homepage until I redesigned this site in 2012.
The experiment consists of two steam images in addition to the main train image. The experiment plays with opacity and small adjustments to position. jQuery to CSS3 transition support is provied by the excellent jQuery Transit plugin.
