Kim Ki-Hong (often just called "Mr. Kim") worked for Bell for many years (The phone company? - NO, not the phone company-He must get asked that a lot...) and is quite the genius. I commented on the "gold look" of the building behind him, for example, and he explained how it's made of ultra-red stopper (not "filter") to trap the heat in the building and lower the heating cost. Wow! A man of many stories and unlike most, they're not all HOT air....pardon the pun, ha!ha!
