For starters, there is a nice big/bold sticky nav bar that follows you all the way down the page. When you scroll over each picture and corresponding headline, the picture fades a bit and the headline becomes orange.
In the features section there are much larger photos and, when you scroll over them, it shows the photo credit in the bottom right corner.
There is also a tab that reads “Read” or “Watch” in the top right of these photos that turns orange when you scroll over them.
Nothing too complicated or gripping, but I think it gets the job done.
