I especially like that you can see the machinery at work, it's not all hidden behind guards (the down side being noted in Tom Jenkins' post above). Yes, it's potentially dangerous but notice that no one seems in a frantic rush. I noticed also the lack of safety admonishments. Where I work it's become positively visual clutter with all the posters, slogans, black and yellow tape, etc.
