can I make stickbar go away?

[pleasedtomeetu]

1) Script Title:
sticky bar
2) Script URL (on DD):
http://www.dynamicdrive.com/dynamici.../stickybar.htm
3) Describe problem:
what javascript will I need to add to add a third option to the sticky bar, where when a button is clicked the whole thing contracts out of sight.

Basically, I would like the code so that I can add a "hide toolbar" link like this guy has on his version of this bar here:
