Change nav text according to the section scrolled into view

Dear Forum. Hope someone here can help me solve this Nav/section interaction…

I am trying to set up an interaction that follows when one of the sections in (the below website) is scrolled into view. See the ‘JD’ in the upper left corner? Next to it I want my project titles to appear accordingly. Optimally – in a snapping movement, coming down from top or below. I essence, what I imagine is that the nav project-title acts as a micro-version (only with a tiny delay) of the sections.

Makes sense?
