The redesign of the engine front-end for the Viggen was extensive and the intake design itself is far from simple and took a crazy amount of design and testing to work over such a broad mach range. Only from more unusual angles or close-up viewing do some of the unique details reveal themselves:

It was a remarkable and arguably unique aircraft.

It looks simple but there are odd things such as the gap at the base of the inlet..... no doubt it took a lot of work to get it just right.

A few years ago I got close to a Formula 1 car and it was covered in tiny detailing that at first glance made no sense but obviously were very, very important.
