I created the skin when I was playing around with Sysmetrix. This resource metering software is very powerful once you get a hang of it. You basically create a background bitmap and place system information on top of it.
This skin here offers most of the resources that Sysmetrix can measure. Time, Date, CPU, Disk, Memory, Network, Recycle bin, Email and some more details.
It was really fun doing it and the result looks really cool.
