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...
A follow up on the creator of this and the clock in Andorra, you can go to http://www.marcdatabase.com/~lemur/dm-gitton.html for more information...
This is a really intriguing clock! "Shopping Iguatemi", in São Paulo - Brasil, has one of these too, with green water.
Interesting... the Shopping Iguatemi in Porto Alegre (Brazil) has one too...
I live in Indy and this thing is cool to see!
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...
