This is a new theme called Abessive. Abessive is a word in English relating to grammar and has foundations in the Latin Abesse meaning to be away/absent. I chose this name because this theme is - almost - absent of images. It does use the core/default images for bullet points.
The theme is 1, 2 or 3 column and has CSS rounded corners. It is floating width and each block has a slight gradient at the top and bottom with the rounded corners.
The theme has been tested on Firefox 2 and 3, IE 7, Opera 9 and Safari 3 and works perfectly (as far as I know) in all of them.
This theme MOSTLY works in IE6. There are a couple of bugs I am unable to fix (The left column keeps moving randomly for some reason and the footer's top border is full width rather than slightly inset).
