人是笼中鸟

A cold universe. Individuals with a cage enclosing a ballon where their heads should be; they come and go in the streets of an immense metropolis. They resemble one another, have a standardised way of life. Some, in a fit of madness or lucidity try to make their balloon fly away, but any such attempt is systematically doomed to failure.... One of them, against the odds, finds a means to escape.
　　一个冰冷的世界里，那里的个体的头被一个关着气球的笼子取代了。他们相遇在一个巨大的城市的街道上，这些个体外形相似，用同一种标准的方式生活。他们中的某些人，因为疯狂或者清醒，试图拿掉那些笼子，可是每一次尝试都失败了。但其中有一个人仍然找到了逃脱的方式。
