I'm pretty much finished with the sunny style. This style set includes a table wrapper as well that adds the slight dropshadow. The table wrapper can easily be used with other colors on a white background as it only adds the dropshadow around the table.
To install, just import the .txt file into your UBB.threads styles and move the 2 images folders in the zip into your styles/images directory.
You can see how it looks on my personal website: http://www.wcsoft.net
