specular highlight on a road - can it be done?

Hi all,
First of all, congratulations for your game vorderman, great!

I've been following this post.. and as far as I can remember, vorderman included a specular function that worked depending on the light position, I guess was a modification of Fredborg..
Could you please point me where can I find that function and media? I would like to implement for the floors..

Thanks a lot!
