Processing Perception

Wandering thru a graveyard in Prenzlauer Berg one morning (one of my favourite tourist pastimes) I encountered this unusual and beautiful marble gravestone with a bold repeating circle design in the place usually reserved for an epitaph.

This stone was the most interesting art object that I encountered during my visit to Berlin’s Transmediale.10.

The dead individual (whom this stone is representing) presents us with a subtle, final-word: a challenge to living-beings.

The ‘optical illusion’ of physical depth against this pristine, flat, surface evidences our flawed and filtered sensory apparatus and disturbs any complacency regarding attempts at understanding the nature of perception (and by extension: space; consciousness; life; and death…)

I have begun working with the design from the stone to test out some ideas in Processing.

(My initial code for the above outline is shared here.)

int a;

void setup()
{

size(500, 500);
background(255);
smooth();
noFill();
stroke(0);
a = 10;

ellipseMode(CORNER);

ellipse(125, 250, 250, 250);

for(int a=0;a<360;a=a+10)
{
pushMatrix();
// move the origin to the pivot point);
translate(250,250);
// then pivot the grid
rotate(radians(a));

// and draw the square at the origin
noFill();
ellipse(-125, 0, 250, 250);
popMatrix();
}
}
