Amsterdam?

Can someone tell me why this icon set is called "Amsterdam"? Where are the corny cloggs, canals, tulips, et cetera that are normally associated with Amsterdam... To the joy of the Dutch the designer freed his mind of all those obvious things and came up with something completely new. Did he get detached from reality or did he just pick a name starting with "A" in the atlas? I just don't get it, sorry icon-buffet-dot-com, you're are just to far-out for me.
