Update this is an old file and I do not suggest you try it on osx LION !!!!!!!
My old custom logon for mac.
The Penthouse logo is animated. (sparkles)
This will also change your buttons on the logon like the preview.
Unzip and place the file in
You will have to change your permissions to read/write
I did not create the images I just sorted them out.
Thanks to [link] omnianimaphobia for the tip to animate the logo.
