Malcolm Gladwell has written an amazing article on Face-reading. Gladwell is the author of "The Tipping Point". His writing style is mesmerising. An excerpt:

All of us, a thousand times a day, read faces. When someone says "I love you," we look into that person's eyes to judge his or her sincerity. When we meet someone new, we often pick up on subtle signals, so that, even though he or she may have talked in a normal and friendly manner, afterward we say, "I don't think he liked me," or "I don't think she's very happy." We easily parse complex distinctions in facial expression. If you saw me grinning, for example, with my eyes twinkling, you'd say I was amused. But that's not the only way we interpret a smile. If you saw me nod and smile exaggeratedly, with the corners of my lips tightened, you would take it that I had been teased and was responding sarcastically. If I made eye contact with someone, gave a small smile and then looked down and averted my gaze, you would think I was flirting. If I followed a remark with an abrupt smile and then nodded, or tilted my head sideways, you might conclude that I had just said something a little harsh, and wanted to take the edge off it. You wouldn't need to hear anything I was saying in order to reach these conclusions. The face is such an extraordinarily efficient instrument of communication that there must be rules that govern the way we interpret facial expressions. But what are those rules? And are they the same for everyone?

Another recent article by Gladwell asks whether smart people are overrated, and says that "the talent myth assumes that people make organizations smart. More often than not, it's the other way around."

From ABCnews.com comes this - it is one of those cool ideas which makes one wonder why no one thought of it before:

Sub Media, cofounded by Spodek and Matthew Gross in 1999, produces 15- to 20-second animated ads that appear on subway tunnel walls. This is accomplished through a series of backlit pictures which Spodek compares to "the frames in a film reel."

The pictures, printed by the U.K.'s Photobition Group on Kodak transparencies, spring to life as the train speeds by, creating a fluid film and giving passengers the effect of being inside a giant flip book.

I haven't yet seen it, but from what I've been told, there is also one in the Hong Kong subway.
