Download Geektool and go into the Shell mode. Then add in four different commands as follows below for Time, Day of Month, Month, Day:
date “+%l:%M %p”
date +%d
date +%B
date +%A
You can then reformat the text and move it to any part of your screen. I believe the weather is through geektool also; haven't figured out how to do that yet but I'm still searching on the web and shooting in the dark on my own! I'll post back if I find out how to get the weather with Geektool too.
Oh, and yeah CoverSutra or bowtie for the itunes graphics. You'll have to get your own pic of a girl or guy though 😉
Edit: I'm pretty sure now that the weather is via a Yahoo Widget.
