Yoda. He never goes out of style. He has been quoted alongside the greatest philosophers of our time. He has influenced many individuals and created a kind of spirituality adhered to by Star Wars fans and their relatives:
Yoda Computer Bobble-Head Ornament
I couldn't think of a better character to perch atop a computer screen, head bobbing and wisdom dispersing as you do... whatever it is you do on your computer.
Here are a few possible Yoda computer ornament quotes:
"Invoices you must print"
"Porn you must not surf"
"Tweet you must"
"Get off Facebook you will, or forever will it dominate your destiny"
May the Computer Ornament be With You
