Magic Self-Moving Droplets’ Whirl

I would like to share with you an autokinetic illusion design project of my creation. An autokinetic pattern is a static image that magically moves like a GIF. You can find this how-to in my new book “How To Draw Incredible Optical Illusions” [you can buy this book from Amazon US or Amazon UK]

After rotating, expanding illusory movements, let’s try something different: a continuous ascending/descending movement of droplets… Here we go.
Draw a triangle and its mirror image as depicted in fig. 1.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 motion.

Starting with the basic cell, prepare now a series of triangle ‘garlands’, each being one diamond-unit larger than the previous one, as shown in fig. 2.a. Resize and arrange then each of these garlands in a imaginary rectangle (fig. 2.b) and set them in equidistant rows (fig. 2.c).

You can decide how many rows to create with this technique; in the example below the pattern 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 can add color or modify the disposition of the patterned columns to enhance the visual motion effect. Now, the black and gray “teardrops” on the left side of the picture appear to be moving up while the ones on the right side appear to be moving down.

Interestingly, with this pattern you can make an experiment to test your dominant side: If the ASCENDENT motion is dominant in your visual field, then you are right-handed. But if the DESCENDENT motion is dominant, then you are left-handed.

I hope you enjoyed my how-to project! You can edit and use it only for your private use, not for commercial purpose. For more information you can contact me through my website.
You can find even more autokinetic optical illusion from my online portfolio.
Prints & products of this pattern are available on RedBubble.
