Update (9 December 12)
I looked at the code for this skin for the first time in about two years, and I was too embarrassed not to clean it up.
The skin is now much smaller and more efficient.
In addition, whatever "lag" I was experiencing with Rainmeter's PLAY bang seems to have been fixed over the years, so I removed the extra addon. This should improve the skin's performance and eliminate some of the problems described in the comments.
-----------------------Update: RMSkin (20 November 10)
I've coverted the package to the ".rmskin" format, which makes it quick and easy to install new skins in the latest version of Rainmeter.
This skin was made from a conceptual mockup by emiko
; I loved his unique original design so much that I decided to take on the project myself.
Along with the apps and labels for each button, you can also easily customize:
Text font, color and style.
Gap between buttons.
The text and the buttons will automatically adjust to each other, so you can make this fit just about any arrangement that seems to be crying out for a 3x3 grid of clickable dots.
The skin also uses a copy of JSMorley's new sound-byte app for the hover effect. You can eliminate this and use Rainmeter's internal sound player bang, but it causes a significant lag when used in this manner. The default sound, which is just taken from Windows' system audio, can be easily replaced as well.
