UrClock

Hello,
This morning I did not have class so I set out to develop a digital clock. I called UrClock ("Your clock"), it could serve as a gadget for Windows, Linux and Mac. It is coded in Java. It is discreet and fits easily into the office environment, in addition to being very lightweight in memory and process.
I tried Windows 7 and Linux 13, but does not have Mac so I could not try it, please send me your impressions to any améliorations. This application is available for download here: http://dl.dropbox.com/u/70990159/Urclock/UrClock.zip

It is in jar format :)
Thank you.
Samuel
