Wow, very nice. Will it run multiple instances or multiple clocks? I'm currently using Qlock http://www.portablefreeware.com/index.php?id=1201 for that and have about 6 clocks for various timezones. This looks much more powerful.
I don't think multiple clocks is possible. Multiple instances is, but not sure about saving the different clock settings... will have a go at it later.
