Australian artist Guy Whitby, aka WorkByKnight (WBK) makes keyboard key mosaic portraits of famous people.
Using his skilled hand in photo manipulation, WBK produces every piece with close attention to each neatly aligned key that serves as a single pixel. Instead of getting lazy and using the same shape in each square slot, simply assigning the space a different color, the artist utilizes the assortment of buttons found in a diverse mix of devices and designs. The result is a really impressive, time-consuming body of work.
In case you have trouble making out the faces in the portraits, take a step back and take another gander.
