Most people want their furnitures to last, but not Ate Atema! His Auto-Cannibalistic Table (made in collaboration with designer Amy Campos) made from egg cartons and wheatpaste glue, is designed to be planted with herbs which "eat away" the table as they grow:
Why can't a table eat itself? Tables support food, but why can't they BE food too? The Auto-Cannibalistic Table understands that in nature energy and matter are in a constant state of transformation, cycling and recycling. It understands these facts and its design explicitly celebrates them. The Auto-Cannibalistic Table is made from paper egg flats, flour paste, soil and seeds, and when water is added, the seeds germinate and so the table begins to eat itself.
