Digital arts 20 - Drawing - Squares

Using simple shapes, such as squares,  I expected amazing graphics with be produced with different combinations of G'MIC filters.  What graphics can be produced and how do they look like? Who knows? Just try. This time some squares were used.

The very beginning simple drawing.

With filters Raindrop, Anguish and Finger paint applied.

O1

With filters Colored pencils, Morphology painting and Raindrop applied.

O2

With filters Lyleyk;s painting, Finger paint and Graphic novel applied .

O3

With filters Posterized dithering, Kaleidoscope [blended] and Painting applied.

O4

Setting  O1 as Dissolve and 80% opacity with O3, the following was obtained.

By flipping O3 vertically and setting  the layer to Multiply and 40% opacity with O3 itself, the following was obtained.

There are many and many different combinations and the outputs cannot be predicted. In order to obtained a satisfactory graphics wanted, many, many, hard works are needed.
