Here is my collection of scripts:
http://www.cattail.nu/mac/GeekTool/
You can download the whole collection or pick and choose. It's got a lot of "standard" scripts (calendars, RSS, system statistics), but uniquely, it includes: a small-footprint iCal event dump program, a network traffic sniffer (requires tcpdump), and parameter driven scripts (for how many entries of things you want to see - useful for top processes, RSS).
Enjoy!!!
