The Aral Sea in Uzbekistan, formerly one of the largest lakes in the world, has been drying up since the 1960s and is currently 10% its original size. Peter Vojtek made a 3-D paper model that shows the shrinkage — from 1957 on top, down to 2007. Each layer represents the surface outline during the corresponding year on the right.
Vojtek also provides his paper template in case you want to fashion your own box. Nice.
