I decided to create a physical object that had physical pixels. This is my process and how it turned out :

I just used around 450 10 inch #3 nails and hammered them into a piece of found wood. Then using your artistisc eye, just paint an image using the nail heads as physical pixels. I was lucky enough to have my picture turn out just right to give the general sense of seeing the famouse image of David Bowie's Aladdin Sane.
