Frequently the clever stuff is the result of the graphics designer having just discovered a library of Flash effects which are so entrancing that they simply have to be used. I suspect something of the sort occurred with Field Operations.
The site opens with the practice name in san serif across the middle of the screen with a 'FO' logo down the bottom left. Hmmm. Much exploring and clicking with the mouse and then two vertical bars eventually appear top left. One labelled 'work' the other 'studio'. On some websites these are interchangeable with each other. OK, so click 'work' . A series of vertical bars of different lengths in black, grey and one in green rotate randomly and, depending on the location of your cursor, fast or slowly about an axis somewhere in the middle of the screen.
Also rotating are words that are attached adjacent to the tops of the rotating bars but because they change so rapidly you can't quite catch their, er, drift. Fed up, you click and a big diagonal rectangle appears and straightens up. Look I'm not going on, other than to warn you that in most of the sections your understanding of what's going on depends on you getting up from your seat, rendering your torso and head horizontal and trying to read the long lines of vertical text. These guys are probably landscape designers but who's going to bother finding out?
