鐵花窗曾經是台灣早期隨處可見的景象，從1950年代左右人們開始在窗戶前安裝具有圖騰的金屬花窗以防止小偷進入家中。

但鐵花窗很快就不僅僅是一種防盜措施，它們變成了另一種日常生活中的藝術，並隨著時間鏡頭調整到現在，花窗早期的防盜功能漸漸移覺成一種「家」的意象。

RACCOON數位製造工坊以鐵花窗作為設計的出發點，將鐵花窗的圖騰元素作為此裝置的主體造型單元，透過離散設計的方式將單元排列出引人入勝的視覺效果，並以數位製造的方式翻新傳統鐵花窗的創意和語彙。

Window gratings were once a ubiquitous sight in Taiwan. Starting around the 1950s, homeowners began installing stylized metal barriers in front of their home windows to keep out thieves. But window gratings soon became more than a theft-deterrent. They turned into elaborate art that reflected the tastes and interests of those who commissioned them. Today the theft-deterrent function of the window gratings gradually shifts into a home concept. We use window gratings as a design concept, using the totem element of the window gratings as the main modeling unit of this installation. Arrange all the units to create a fascinating visual effect through discrete design. The production method of Pattern Light renovates the creation and vocabulary of traditional window gratings in a digital manufacturing method.
