If you haven't already come across him, Christian Zuzunaga is the undisputed king of all things pixellated. He's a London based fabric designer who has collaborated with the likes of Ligne Roset and Moroso.
Designer Benjamin Rollins Caldwell of BRC Designs has put a witty spin on his block based cabinetry with his 'Spineless Side Tables' and his 'Label Whore Cabinets' made from old book spines and jeans tags. Other pixelly collections of his include his delightful (if impractical) Abc123 kids collection, and his magnificent Concreations.
No pixellation list would be complete without a nod to Rod Arad's Do Low Rez carpets and blocks. The colour combinations are superb and they will lift the mood in any room.
