PixelSpirit Deck

by Patricio Gonzalez Vivo

Each Pixel Spirit card presents a visual element together with the GLSL shader code that generates it. Ultimately, these elements can be reused and combined to compose an infinite visual language. This deck is a tool for learning, a library, and an oracle.


The cards are ordered as an unfolding continuum that goes from simplicity to complexity, from darkness to light, so they can be learned and memorized easily. Through this progression, the cards present new functions, creating a library of functions that can be reused and combined like a portable book of spells. Within the 50 cards of this deck you will find the 22 major arcana, the ancestral archetypes of the traditional Tarot deck: the wisdom of these powerful cards will guide you.

If you are thinking on going through the cards to teach yourself shaders consider using the following online editor:


Compile the cards

  1. Install glslViewer following the instructions from here

  2. Compile any of the cards by:

    glslViewer 00-elements/000-void.frag
    glslViewer 00-elements/001-justice.frag
    glslViewer 00-elements/002-strength.frag
    glslViewer 00-elements/004-the_wall.frag
    glslViewer 00-elements/045-inner_truth.frag 
    glslViewer 00-elements/046-the_world.frag
    glslViewer 00-elements/047-the_fool.frag
    glslViewer 00-elements/048-enlightenment.frag

If you want to make PNG images of them you can do something like:

    glslViewer 00-elements/045-inner_truth.frag -s 1 -w 448 -h 748 -o innerthruth.png

You can also compile them and watch the one by one for 5 seconds like this:

    find . -name '*.frag' -exec glslViewer -s 5 -w 448 -h 748 {} \;
