By architectural firm Arakawa and Gins, Tokyo. Sun Tsu at Weird Asia writes:
Painted in eye-catching blue, pink, red, yellow and other bright
colors, the building resembles the indoor playgrounds that attract
toddlers at fast-food restaurants.
Inside, electric switches are located in unexpected places on the
walls so you have to feel around for the right one. A glass door to the
veranda is so small you have to bend to crawl out. You constantly lose
balance and gather yourself up, grab onto a column and occasionally
trip and fall.
Arakawa says â€œ[The apartment] makes you alert and awakens instincts, so youâ€™ll live better, longer and even forever,â€ says the artist.
I don't know about the purported effects on life span, but the building is extremely cool
