Reload only half of the page

Is there something that i could do to split my website into 2 parts so that only half of it reloads. then on the other half i could have like a timer or something.

if you want to see what i mean you can go here.

I want the top half to reload and the bottom half to stand still so it won't reload. so it can tell you how long you have been there.

use frames. in one frame use a META refresh.

my work here is done.
