Artist Federico Pietrella has a clever and impressive way of "printing" his photographs. After selecting one he wants to use, Pietrella recreates it by hand using nothing but a date stamp and ink. Pointillism is usually done with distinct dots, but each of Pietrella's dots are a short row of numbers indicating the current date.
The Portrait Project is a series of 10 stitched portraits by London-based artist Evelin Kasikov. Each portrait is created with an actual Polaroid picture as the starting point, and is based on the same grid. The idea is similar to pointillism, but instead of dots she uses squares, crosses, and lines of different colors and weights. 10-15 feet of cotton thread does into each piece, and stitching them takes between two days and a week to complete.
