20080818

Here is a 65536 x 65536 pixel image of 20080818. This work is based on an "Invaders" pattern, piled at various scales.

"Invaders" refers to Space Invaders, one of the first informatic game, released in 1978. This game consisted in shooting from a spacecraft on extraterrestrial "invaders". Because of the poor resolution of the computer screens at this time, the latter were coarsely represented by two color 10 x 10 pixel matrices.

The "Invaders" pattern divides the plane into squares, and further divides these squares into pixels (here each square is divided into 5 x 5 pixels). It attributes randomly to each of these pixel an index value among two possible one. Interestingly, if one forces a vertical mirror symmetry on each of these pixel matrices, and provided the number of pixels is not too big, patterns reminiscent of Space Invaders appear.

This pattern was inspired by complexification.net.
