When I go there it is below the fold so to speak, so with my browser settings / video resolution, I don’t see it unless I grab the scroll bar and scroll down. I would simply put it as “click/drag” from side to side or scroll the mouse wheel (if you have one) up for more recent and down for older. Something to that extent.
I’m not trying to criticize, merely trying to help. I think what you’ve done is pretty darned cool!
What? The timeline starts like an inche and a half from the top of the screen....
What resolution are you using?
