Joomlashcak have released two more themes for Joomla 1.5 for their back catalogue.
I won't go over old ground about these themes as you'll find all the information you need here.
I will gently remind you however of the theme builder they're now giving you access to at Joomlashack - it's a first in Joomla and one that basically means you can crate your own absolutely unique theme.
