Michigan based artist Eric Daigh creates detailed portraits using thousands of push-pins into notice boards.
Daigh begins his portraits with a digital photograph of his subject. He then uses a computer to create a low-res five-colour image using the primary colours of red, blue and yellow, plus black and white. He then produces a grid map showing him where to stick the pins, row by row.
Daigh's biggest portraits are almost 2 metres high (6ft 6in) and use more than 20,000 pins. They can take around eight months to complete. The 32-year-old also holds the Guinness World Record for the biggest push pin mosaics.
