I just finished a theme called Themis, and would like to share it with you. Its less graphic-intensive this time and perhaps more "allround". You get the option of putting a logo (picture) on the top of the board - check "current themes settings" in admin panel.
This one doesnt have buttons with text. It can be just the icons - or icons with text-strings next to it/below it. There is a line on the front that says "most users online ever" and "most users online today"- and the main buttons on top can have labels.(shown in the screenshot). Configurable in the admin section along with the logo. The linktree is "boxes-only" inline style and has hover-effect.(should work in both mozilla/opera along with IE). Graphics may only be used in a SMF enviroment.
The theme has three extra fields in "current Themes settings": Sidebar..put your HTML code in here and it will show upp on the left. If empty, sidebar will not be visible. Sidebar width.. set the width of it in pixels. Topbar..put your HTML code in here and it will show upp on the top - above the upshrink. If empty, topbar will not be visible.
