This beautiful "Bubble Tank" that's about to fall off the table was created by Sheffield-based design studio Psalt Design. Just looking at this fish tank makes me uncomfortable, however it "is resting on its counter-balanced weight" so there's probably nothing to worry about. Made from premium glass, handblown and slumped by a master glassblower each tank has it's own unique form and individual characteristics. (Available for £295 at psaltdesign.co.uk)
