Watch the Picked Arpeggios in Motion online guitar lesson by Rich Maloof from Guitar 201: Breakthroughs
Picked arpeggios can be used really nicely to produce a kind of rolling, almost hypnotic effect. The key is keep them moving — steadily moving — through the changes. In this example the pattern employs a low-string strike followed by upstrokes on the top 3 strings. Start slowly! You may want to run it a few times before starting with the backing track. When you're ready to try it at tempo, keep good steady time throughout the pattern.
