You haven't read the title wrong, seven new themes have been released for Joomla and they are all free and you can go download them now.
They are introductory themes and TemplateWorks will be releasing themes that you have to pay for soon and while this hasn't been confirmed, prices I think are going to be very competitive. We will have to wait and see, but it won't be too long.
The themes they have released so far are all very simple, clean and from simple tests I have performed, fast loading and SEO friendly. Well worth a look if you are looking for something simple yet very effective.
TemplateWorks are part of JoomlaWorks and if you've used one of their products you'll know that they are good and they are also the guys bringing us K2, something I am playing with and one day you might see here and something that is sure to take Joomla to the next level.
I think there may be more to come from these guys too, time will tell. Click here for more information or a demo.
