[(un)Useless Machine] is a series of gadgets with aesthetically useful yet practically
useless functions; the un-uselessness is embodied with three dimensional spatial collages of useful parts fetched from daily life and each series interprets the prompt differently. In general, the project seeks to imagine the aesthetic possibilities of some underrepresented daily objects.

The first version of the series takes the angle of a human's five common senses, the senses being smell, sight, touch, sound and time (in replace of 'taste'). The machine has two general layers. Inspired by the traditional wooden puzzle, “魯班鎖 ”, an old Chinese Joinery technique, the first layer is a self-holding metal lock which if assembled in a certain sequence, it requires no screws or nails to stay compactly together. Then, the second layer is composed of mechanisms that are, in general, mechanically interactive and can response to the five senses.

Lastly, the first layer, as the vessel, is interlocked with the second layer, creating a compact machine at the size of an adult's hand.
