One night late at 2am (when my creative juices are flowing like a raging rapid), I decided to customize my own Word Press theme geared towards Trinidadians. The theme has all the colours of the National Flag of Trinidad and Tobago.
One user said it does not work properly in Word Press 1.5. I have not tested it in 1.5 but it works in versions before that. I have not had the time to upgrade it to 1.5 as yet. Sorry.
The theme is called Trini Press and it is mentioned on the Word Press theme list website.
You can download the Trini Press theme and freely customize it.
