My friendly and knowlegable Korean wife confirms Mcgrude's guess: it is in fact a how-to guide for (creepy) guys to get the best view, both in angle and distance.

If my math textbooks had presented geometry like this I might be working for NASA now.

The seats look to me like typical opposite-side-facing Seoul subway cars. Perhaps another page says this explicitly.

Anechoic: "If only all airports were as nice as Schiphol!"

Schiphol wants 6 Euro for 30 minutes of wifi, or 10 Euro for 24 hours. You really need to want to check your e-mail at that rate.

Schiphol is indeed aesthetically nice, particularly compared to other Western hubs like LAX, Heathrow or JFK, but it can't hold a candle to Kuala Lumpur, Singapore's Changi, and other free wifi, comforts aplenty Asian airports.
