The graphic design '404 not found', displayed in 'Eco Expo' in 2019. In the graphics, multiple pixel layers repeat their appearance and disappearance being damaged or transforming into new images. There are layers implying the concept of plants being artificially selected or vanishing away. The layer cover up the previous by cheaning its ratio. This represents the gap between the original plant and the artificially selected new concept as in the 404 error.
