South station towers glass doesnt seem to be much more reflective or silvery than millennium tower or winthrop tower when the sun isnt hitting it, but it seems like its angled perfectly towards the setting sun in the west that it absolutely lights up every day as the sun is setting and shines like a mirror. Pretty cool effect! In the bottom pic you can see a few of the pleats on the right side of winthrop place catch the sun too, but its nothing like the entire broad side of sst. Somehow the angle worked out just right that it shines like crazy at the end of every day. It looks like our own archimedes heat ray at the siege of syracuse.
