The same image, before and after applying Cubism filter
You can find this filter in
The Cubism plug-in modifies the image so that it appears to be
constructed of small squares of semitransparent tissue paper.
If setting possibilities of this filter are not enough for you, see
which offers more options.
“Cubism” filter options
This variable determines the size, in pixels, of the squares to
be used. This is, in effect, the size of the little squares of
tissue paper used in generating the new image. The slider can be
used, the exact pixel size can be entered into the text box, or
the arrow buttons can be used.
This variable specifies how intense the color of the squares
should be. This affects the opacity of the squares. A high value
will render the squares very intensely and does not allow lower
squares to show through. A lower value allows the lower squares
to be more visible through the higher ones and causes more
blending in the colors. If this is set to 0 and Use Background
Color is not checked, the entire layer will be rendered black.
If it is checked and the value here is zero, the background
color will fill the entire layer.
This filter creates its tiles from all the colors of the image
and paint them with a color scale which depends on the Tile
Saturation With a low Tile Saturation, this color scale lets the
background color appear: default is black as you can see by
setting Tile Saturation to 0. When this option is checked, the
background color of the Toolbox is used. If your image has an
Alpha channel, this color scale will also be transparent.

If you are using this to generate background images for web pages and
the like, work with a small range of colors painted randomly on a
small square. Then apply the Cubism filter with the desired settings.
As a last step, try Filters/Map/Make Seamless to adjust the image so
it will tile seamlessly in your background.
