The Grove glass staircase rippling

An ifoAppleStore tipster has taken a few pictures (one seen at the right) of the 'rippling' that is happening on two of the panels of the glass staircase in the Grove (that's the Apple store in LA). This isn't structural damage, meaning that the staircase is still as safe as ever, it just doesn't look as pretty.

I wonder how long it'll take Apple to replace those rippled panels (and how much it'll cost them).

Oh, and in case you were wondering, it is a slow news day.
