時間如同河流，不斷沖刷際遇的同時，也在積累豐富的記憶。擁有多媒體影像設計背景的團隊「友意國際」，在〈光動能〉中藉由光影交錯的變化，將抽象的時光具體為視覺與影像的互動裝置，透過觀眾的親身介入，去改變和體會作品所呈現出的不同效果，除了拉近人與人的距離外，也創造出人與藝術交會的美麗風景。

Time elapses as if it is a flowing river. In the course of time, we not only experience vicissitudes of life but also accumulate a wealth of memories. With a background in multimedia image design, the Unison Art Association transformed abstract time into a tangible imagery interactive installation by weaving light with shadow in Photo-dynamism. The visitors will change and experience the diverse effects produced by this installation in an immersive fashion, which not only shortens interpersonal distance but also creates a charming scene where people meet the arts.
