錯視設計 |底爾帕夫錯視 Delboeuf illusion
一種對實際大小知覺上的錯視。客觀上其實兩個同心圓的內圓是相同的，但在主觀上，我們會以為小同心圓的內圓較大。

設計理念 |
即使是同一圖案，也會被視覺假象騙過；即使是同一事實，也會被傳達的人給擅改。背景用了臺灣社會最通用的政治色彩來暗喻操控民眾想法的兩方勢力，其實若是可以鄙棄外在條件的話，可以明確了解到他們並無分別。

Even the same size square inside the circles, even there is only one truth, we might be cheated from someone or some illusions.
The blue and green backgrounds used in this two circle mean the two biggest political party in Taiwan, and its also mean the situation that both of them try to control peolple’s mind. But, if we erase the background, check the things yes or no by using our eyes ourself, we will become ourself’s destiny, and we will never so hesitate all the time.
