There's a lot of info packed into this clock. The inner dials show CPU usage, Drive C: use, physical memory use, and a dual time zone that's configurable and currently set for Western Europe Standard Time. The lower switches indicate the presence of unread email messages and whether there are files in the recycle bin. Finally, the upper text indicates the outside temperature and the current day. All this in pseudo shiny glass and metal!
You'll need version 3.03 or greater of SysMetrix for this theme to work properly.
