Journals are usually hidden away under a mattress or secret compartment, but Cristian Marianciuc’s daily journal is meant to be seen and shared by people all over the world.

Named the 365 Origami Crane Project, Marianciuc’s journal has taken the form of one beautiful paper crane folded every day since January 1st, 2015. By utilizing various combinations of paper, colors, textures, and light, he expresses his daily thoughts through his creations.

The idea to make origami cranes was inspired by Sadako Sasaki, a young girl who lived in Hiroshima when the atomic bomb was dropped in 1945. After being diagnosed with leukemia ten years later, she decided to fold 1000 paper cranes to have a wish granted. Unfortunately, she perished before she could fulfill that goal.

Marianciuc was also inspired by another special person — one of his sisters who passed away of leukemia.

To honor them and to drive himself to make the most out of life in 2015, he began the origami project.

“Looking back at my cranes, I can, at a glance, remember at least a tiny detail about the day in which it was made. And that makes me emotional, but also extremely thankful,” he told Upworthy.

Here are just some of his unique paper cranes, more of which can be enjoyed from his Instagram and Facebook.
