061126 Light Tracer
紐西蘭27歲的年輕藝術家Karl D.D. Willis製作的的光塗鴉（Light Tracer）是這次藝術與科學研討會我全程接待的作品。這是個交互的牆上”創作工具”，容許使用者或者玩家透過任何的光源在屏幕盎书写，涂鸦，绘画和描摹图像。光源由簡單的數碼錄影機追踪後显现在眼前的背後投影的显示屏幕上。这个藉由光線的塗鴉系统可以用來用它来书写字距或者信息外，也可绘图或者描摹脸、手任何透過光源產生的圖像。
Karl 離開北京前我安排他做一個小型的公司內部演講，舉辦的地方是在紅鶴溝通，北京最前沿的地產策劃與廣告公司，關於他的演講、作品詳細說明、以及個人簡介請見紅鶴網站的”新媒体交互走红日”以及下面的英文說明。同行的還有初次見面便覺得非常熟悉的北京在地藝術家温京博，他目前在德国卡塞尔艺术学院攻讀新媒體藝術碩士，此次它的作品Swirl也參加了此次第二屆藝術與科學展覽。
Short Description:
Light Tracer is an interactive installation which invites the participant to write, draw and trace images in real physical space. The participant is situated in front of a screen reflecting their own image, and by manipulating a series of light sources the participant can leave marks on the screen such as drawings, messages, and trace out physical objects such as faces, hands and bodies.
