I realize that I'm dating myself by including a link-list here, but I can't help myself. These are a few of my favorite things and, if they're not already, you should consider making them your favorite things too.
Astronomy Picture of the Day - If you don't feel insignificant enough already, this site should help. The universe is really, really, really big.
The American Southwest - One of the things that convinced me to move to Las Vegas was it's proximity to all this natural beauty.
Deviant Art - There are some very creative people out there, and I'm not ashamed to borrow on their skills to fule my imagination.
Lifehacker - Full-of-Awesome HowTo's for making life better. My Nerds. For Nerds.
