This geeklet will list today's tasks from your Things database.
You need to install the Ruby Gem "things-rb" first so this might need some coding experience. See the things-rb homepage (http://github.com/haraldmartin/things-rb) for installation instructions
If you want to show other tasks (than today's), just change today in the command field to inbox, someday or something. Again, see things-rb homepage for options.
