Space Invaders at Work
6 business cards can be folded into a self supporting cube, those cubes can interlink with each other and form much larger structures. My initial idea was to fold the cubes with the text on the inside so as to create white cubes and text on the outside to create coloured cubes. With 2 different colour cubes some basic pixel art images become possible. The instructable below shows you have to create these card cubes and how to link them together to form a wall of cubes.
