After seeing a few Star Trek themes that all avoided actually making an LCARS style, I decided to give it a shot.
This theme contains two versions. One is a classic LCARS color style, the second is a custom color scheme in more Blue tones. There is a style select at the top to easily switch between the two. Different links, mouse overs and images will blink to add to the LCARS feel. A Ranks folder has also been included in images for use with member groups. Included Rank images are: Captain (shown under "Additional Screenshots"),Commander, Lieutenant Commander, Lieutenant, Lieutenant Junior Grader and Ensign.
As an addition, there are two background files with "-right" at the end. These can be used to make the LCARS images and inner bar face right. To use them, replace bglcars.png with bglcars-right.png. Same for bglcars_classic.png. They can be found here.
The extras.rar contains all PSDs for the theme, a Star Trek favicon.ico and the LCARS font (Swiss 911). To use the font, follow the instructions at the top of the CSS files for the theme. (Note: If you use the font, your members will have to have it on their computer for the site to be viewed properly.) The zip also contains an alternate version of bglcars_classic.png that is flat colors with no shadowing for more authenticity. To use it, simply move it to the images folder. It also has a folder for TinyPortal images for those who use that mod.
