I used to have this clock on my old PC in Japan many years ago whilst running Windows 98.
In the process of three updated PC's later and the new Windows release, I somehow lost this clock along the way, although It probably wouldn't work with Windows XP.
Unfortunately, the link appears to be dead, as this was an awesome desktop clock!
It looked much better in the real and was fully customizable
If anyone has this programme, please let me know as I have a few friends who collect in Japan and they also want this
