One of the most influential products to come out has been the Apple iPod. It has revolutionized the way people listen to music. The iPod has taken many shapes and sizes. One of the most popular has been the Nano which uses flash memory storage and is razor thin. Looking at my daughter's iPod Nano I thought it would make a great subject for a Plurk theme.
I developed this theme for my daughter who wanted something themed around the Apple iPod Nano and it has a few interesting features that you might find helpful.
Some of the more interesting features include the use of a red and a green iPod Nano icons to identify new Plurk messages and replies. 
An unread message shows a red iPod Nano with red numbers while a read message will show a green iPod Nano with green numbers. This is slightly different than the typical colored box that you see. For those who don't want to see their Karma score, I have replaced it with Apple CEO Steve Jobs.
The loading graphic in the timeline has been replaced with an iPod commercial graphic. This will appear whenever you scroll through your timeline left or right. There is also a new loading graphic in the response box. This one is a rotating iPod Classic in a small animation.
The scroll left and right arrows have also been replaced with blue iPod Nanos. When you hover over it with your mouse it rotates to its side with an arrow that points which direction your timeline will move. The "Back to Home" blue button has been replaced with an Apple logo. When you hover over it with your mouse the logo changes to the old style rainbow Apple logo.
The Plurk creature has been removed and replaced with Goofy wearing a Diamondbacks uniform.
I think you will find this theme fairly full-function with a lot of detail added. If you have questions please feel free to contact me. I hope you enjoy this theme and be sure to tell everyone you got it from Plurk Skins.
Update: This theme has been updated to reflect the changes made to Plurk through January 13, 2009.
