About This Design

Impossible triangles geeky pattern postcard

Impossible triangles geeky pattern postcard

This impossibly geeky geometric pattern is created by a series of impossible triangles. These apparent 3D shapes are a famous optical illusion, which tricks the brain into trying to make 3D sense out of a 2D image, and confusing it. This geometric pattern alternates between warmly colored and cooly colored impossible shapes, to create a colorful, fun pattern. This geometric design looks great on a wide variety of products, and it is a great gift for math nerds, or surreal art lovers.

Creator Review
I had never seen these classic science fiction images and most of my friends have not seen them either. They are like little treasures! Amazing quality and fun to send people!

I joined Postcrossing a few months ago and wanted postcards to represent my state well. I found them on Zazzle. I purchased numerous cards and was impressed with all of them. Excellent! The colors are beautiful. The cards have the exact look I wanted. I couldn't be happier.
