This installation, first exhibited in Berlin in 2006, is a metaphor for how mankind finds itself in one historical tragedy after another due to its blind sense of obedience. He reminds people that, even though the Berlin Wall has been torn down, "The invisible walls are harder to raze." That glass wall represents the wide gulf in mental outlook of the East and West German people.
這件 2006 年在柏林首展的裝置藝術，意在隱喻人類的盲從，導致歷史悲劇一再重演；他也提醒人們，柏林圍牆儘管已經拆除，但「看不見的牆更難拆」，那堵牆，正是東西德人民心中無法跨越的鴻溝。
