The interesting part of the panel is that it displays "Who is the terrorist?" on the front side, and shows the answer at the back……誰是恐怖分子?從動物角度而言,人類是恐怖分子。用水過度,導致牠們的棲息地變乾;膠袋處置不當,污染海洋;浪費紙張,因而砍伐更多林木。我們要喚起人類良知,停止浪費地球資源,不再做恐怖分子!我們於是設計這三張海報。為了引起更多公眾關注,我們計劃在地鐵設立裝置。裝置有兩個部分:一、機械獸,模擬垂死的動物不斷喘氣。二、單向的玻璃廣告面板。面板巧妙之處,正面顯示:「誰是恐怖分子?」,背面則顯示答案……
