They used Flash but it incorporates some navigational devices used with HTML5/CSS3, like vertical scrolling. I got the tip they’re moving into that direction, and sometime soon maybe we’ll see pure HTML/CSS coded interactive narratives.
They incorporated 360º panoramas from the top of the tower and video. It’s simple, cool, I’m not a big fan of their design style but it works pretty well.
JN is one of the few media organizations that consistently create interactive and multimedia narratives in Portugal.
