Twitter Feeds (the easy way)

Once you open GeekTool, open a new Shell Command and enter the following information:

curl -s -u username:password http://twitter.com/statuses/friends_timeline.rss | grep title | sed -e 's/<title>/ /' | sed -e 's/<\/title>/ /'

(NOTE: Insert your Twitter user name for username: and your Twitter password for :password)
Change the fonts, colors, etc. to whatever you choose and Voila! You’ve got a feed on your screen.
