The interaction between unit and aquarium creates a surrealistic effect without initially revealing the underlying engineering. The upper, rectangular ‘block’ conceals the aquarium lighting, a cable shaft and an inspection cover for large maintenance jobs. The filter system is installed in the left-hand cabinet section and can be accessed via a pull-out drawer system. The remaining lower section can also be revealed using a drawer system and can be used as storage space. The design clearly reflects the Tetris game block.
