Cool, but...
...about fifteen years ago when the city of Amsterdam was starting work on the suburb of Ijburg, they had a visitor centre with a model of the finished suburb where they used old semiconductors to represent the buildings.
OT: Ijburg was, in classic Dutch style, built on reclaimed land. (I sailed over it before they reclaimed it). It nowadays gives me the opportunity to shout as I drive past it "I remember when this was all just lakes!".
