Geektools

I recently came across this mac application where you can customize your destop with widgets called geeklets.

Download it from

http://www.macosxtips.co.uk/geeklets/about/

This is a partial screenshot of my desktop

Drag the Shell icon to your desktop

In the properties, use the following terminal command for the hour:

date '+%H:%M'

font: Helvetica Neue light 150

for the date:

date "+%A,  %B %d - %Y" 

font: Helvetica Neue light 36

and for the calendar: 
just "cal"

or if you like to start on Mondays:

cal | awk '{ print " "$0; getline; print " Mo Tu We Th Fr Sa Su"; getline; if (substr($0,1,2) == " 1") print " 1 "; do { prevline=$0; if (getline == 0) exit; print " " substr(prevline,4,17) " " substr($0,1,2) " "; } while (1) }'
