Creative coding: Johan Ismael
Art direction: Anthony Dodero

Using an internal tool that eventually became Meta Spark AR, I implemented an augmented reality drawing tool that shipped in the main Facebook mobile app. The vertex shader was used to taper the drawing geometry while the fragment shader implemented an animated gradient and light fresnel rim.
