An interactive version of the diagram on Te Ara’s Rocky Shore page, made in Articulate Storyline 360. I made a basic wave animated gif in photoshop for the water level to make it a little bit dynamic.

I had a bit of back-and-forth between using layers or states for the water level and the zone labels. I found layers would appear over the top of the buoy slider, preventing it working. In the end, I used items with states for the zone labels, water levels, and the labels on the sealife.
