 Version 1.8.6 Compatibility :  Firefox:  2.0 – 2.0.0.*

Metal Lion 300 Preview

Inspired by the film 300, this theme has been designed to have a long lasting appeal to both fans of the film, but equally to those who have never seen or heard of it. Whereas other themes of mine have concentrated on gradient and/or 3D effects, this theme explores the interplay of colours and also the use of transparent effects. Also not being constrained by having to stick to a Vista or Mac look, has also meant that I am able to let rip on this one.

All icons and graphics used in this theme are designed, created, made and copyrighted to Frank Lion, with the single exception of the helmet image used in the Theme Preview (heavily reworked) and Downloads windows which is used by the kind permission of

I hope you enjoy using this theme as much as I enjoyed making it.

Known Issue -  AIOS extension.
