The built-in tile themes that ship with Tk 8.5 don't look very fancy on unix/linux platforms. A number of additional themes is being maintained in the tile-themes module of the tktable project on SourceForge.
You can obtain these themes by checking them out with cvs:
cvs -d:pserver:[email protected]:/cvsroot/tktable login cvs -z3 -d:pserver:[email protected]:/cvsroot/tktable co -P tile-themes
There are two types of themes:
There are currently (9 Aug 2009) four pixmap themes in the tile-themes module: plastik, keramik, Aquativo, and winxpblue. The last two require some form of PNG support to be available.

The tile-themes module also contains two binary themes: tileqt and tilegtk.
