City glazing fashions - get the look

The glazing at 125 Old Broad Street in the City of London - the former Stock Exchange building - is undergoing a makeover.   This is presumably something to do with the problems that have been reported about glass falling out (a less abstract threat than a falling FTSE).  

The present look, at first glance, bears quite a close resemblance to one of those fashionable facade treatments with diagonal lines that echo (allegedly) the stress patterns in the glazing, such as OMA's CCTV building - or more purely decorative versions of the same sort of thing by FOA and others.   But on closer examination, the pattern here appears in fact to be no more than protective tape to glass awaiting replacement.  Quite neatly done, though - and if you think about it, the visual resemblance to the stress diagram is probably not accidental.
