Thanachart “Benz” Siripatrachai, 26, caused a stir in 2012 with his photography project “Smartphone,” in which he took pictures of people’s reactions after he shouted random words like “omelet,” “alligator” or “Kafka” at them to get their attention while they were using their smartphones on the MRT. Now, he’s gone viral with his new book’s promo clip, “BKK 1st Time,” which has already reached over 2 million views on YouTube. BK chats with him about his book New York 1st Time and his creative process.
