Final answer:
The provided information does not specify why 'David' wants to build a wooden chest but discusses Ai Weiwei's Moon Chest installation and other unrelated artistic works involving wood.
Step-by-step explanation:
The reason David wants to build a wooden chest is not explicitly given in your provided information. Instead, Ai Weiwei, the artist mentioned, created an installation called Moon Chest where he made 81 chests of wood. Ai aimed to achieve simplicity in materials and construction, combined with functionality and artistic beauty. He used Huali wood, known for its use in Chinese furniture and built the chests without joining materials, emulating methods of ancient furniture-making. Although the name 'David' is present in reference to Michelangelo's David and to Donatello's artwork, these do not pertain to the construction of a wooden chest.
Jems Robert Koko Bi, another artist mentioned, works with wood to transform it into images, giving new life and telling new stories. However, this also does not directly relate to any intention of building a wooden chest by someone named David.
