Kotlinconf Logo (origami)
This model represents the logo of KotlinConf, a conference dedicated to Kotlin programming language.
While the logo as pictured on their homepage certainly has an origami-like appearance, I don’t know if it is based on an actual origami model or only made to look like one. Nonetheless, I was able to devise a way of folding exactly the same shape from a single square of paper (duo colored: blue on one side and orange on the other) without any cutting or glue. It was a fun challenge.
