I came up with the idea for this while listening to "Computer Love" by Kraftwerk when I asked myself how could a computer love another one.
I did the modeling in Blender, except for the hearts which I made in ZBrush very quickly, texturing and rendering were made in Cinema 4D. I wanted to give it a cartoon-ish style so I drew the computer faces in Photoshop. It was probably the first time that I drew something exactly how I imagined it! The hardest part was probably setting up the scene because I wanted to fill it and give it depth while keeping the focus on the two protagonists.
I did also a bit of post-production in Photoshop.
