In the extract below I explain how to create a self-moving blueprint.

DROPLETS' WHIRL

Draw a triangle and its mirror paradigm as depicted in fig. ane.a. Add graduated shading to both triangles: one with black to dark gray, the other with gray to white gradation (fig. 1.b).
Erase the contours of the geometric shapes and form the first cell (fig. 1.c), which will allow you to create this amazing illusory two-way movement. how to draw 1

Starting with the bones cell, prepare at present a serial of triangle 'garlands', each being one diamond-unit larger than the previous 1, as shown in fig. 2.a. Resize and arrange then each of these garlands in a imaginary rectangle (fig. ii.b) and set them in equidistant rows (fig. 2.c).

You can decide how many rows to create with this technique; in the instance beneath the design contains just 11 rows/columns.

Finally copy the pattern, rotate it and assemble it with the initial one to obtain a much larger pattern that combines descending and ascending illusory motion giving an overall impression of a droplets' whirl.

You lot tin can add color or modify the disposition of the patterned columns to heighten the visual movement effect. Now, the black and gray "teardrops" on the left side of the flick appear to be moving upwards while the ones on the right side announced to exist moving down.

Interestingly, with this pattern yous can make an experiment to examination your dominant side: If the ASCENDENT motion is dominant in your visual field, then you are correct-handed. Just if the DESCENDENT motion is dominant, and so you are left-handed.
