I've used pegboard to organize tools, of course. And when those fugazi pegboard hooks would fall out, I'd occasionally placed a wood backing behind it and used sheetrock screws driven to different depths to mount tools of different thicknesses (a rubber mallet versus a regular claw hammer, for instance). Of course, it never occurred to me that the screw heads could be painted, that the evenly-spaced pegboard holes could be the basis for pixels, and that screws driven to different depths could be used to create depth perception. And that's why Andrew Myers is an artist and I am just a blogger who writes about artists.
