Inspired by the similarity of experiencing a new world through digital media and falling into a wonderland, the design of this multimedia library combines interior space with the story of “Alice in Wonderland”. The real and the virtual are contrasted as existence and its shadow. At the entrance, users encounter a space that is covered with green shadowing and see two juxtaposed trees. These two arboreal columns situated at the centre of the space are materialised as a metaphor rendering substance and as delusion respectively. What is obviously a substantial tree and an imaginary tree, as expressed by the shadow, demonstrate perfect symmetry within the space.
