H.H.Lim created a new project “The Mental Trip” for his exhibition in Beijing. In the form of double spiral cages, it invites the public to walk through the cage and enter a mental game. They enter and exit the cage in a parallel way without meeting each other, as in the Well of Saint Patrick . Hence, one can “live” in one’s own world. Paradoxically, taking shelter in a cage can make one feel protected. But, in exchange, one is condemned to be cut off from touching the other. This generates a permanent mental tension under the gaze of the other while the other is never an accessible company. Being “appreciated”by the other can be a “pleasure”. But in the meantime, this is the beginning of losing all freedom.
