Multimedia, movement, sound effect and interaction of objects -- these terms are recently representing the recent directions of Tam Kai Fung's works. These are the roots for him to sculpture the beauty of sentiments and relationships of biologicals, and pursue the status between ambiguity and concrete. Growing in a digitalized metropolis, he likes to observe the sophisticated but instant emotion from strangers in daily lives. He experienced how the diversified ways of communication recently changed the direct approaches towards emotional expressions. The depression of the city leads to a lack of true opinions exchange between human beings. For him, the interaction of objects creates new dialogues and connection with audiences. Not to critique but tries to seek out new ways for people to express and re-value that ephemeral information from his work.
