Follow the headline link, maximize your window size (large display, if possible). Tap each of the controls on the upper right of the current sample image, just to get a sense of what each does. I’m a big fan of the loupe (click to turn it on, then drag the mini-window around the image).

I love this interface, wish there was a version that laid on top of a public, crowd-sourced gallery, with the favorite images rising to the top.
