Since I live in Indiana and have a four-year old, I am very familiar with this clock. It is definitely beautiful and functional. When the time changes from 12:59 to 1:00 it is very dynamic and always draws a crowd. In the spring, Indiana started following DST and they had use a spigot to change the hour manually.

I saw a similar clock in Andorra in the spring of 1992. Sitting in a mall somewhere. It was snowing, we had a cup of coffee, and spent an hour or so figuring out the pressure and vacuum system of the clock. I doubt a picture exists, though...

This is a really intriguing clock! "Shopping Iguatemi", in São Paulo - Brasil, has one of these too, with green water.

There's also one in the Europa Center in Berlin. I spend an hour looking at it one day, trying to figure out enough to build one of my own. If anyone wants any hi-res pictures though...
