I'll sort out a proper list of where all my neat script and markup is stolen from at some point, but for the time being I just wanted to confess that the core of my new sidebar-hiding gizmo is ripped out of the Drunkey Love theme for Wordpress, which I learned of through Unreliable Witness. Thanks folks.

I'm kind of hoping the awful button graphics I'm using are temporary, but I doubt I can do all that much better. Graphics really aren't my thing. (Plus they appear in the wrong place in IE)
