Kotlin is a programming language for the Java Virtual Machine (JVM) which is gaining in popularity. Having used it for some time, I’m quite happy about the results and I held a Kotlin birds-of-a-feather session at the recent Devoxx.PL conference in Kraków, Poland.
Since the logo is quite simple and based on geometric shapes representing just the letter K, I couldn’t resist trying to design it in origami. Lacking duo paper with the right colors, I used a three-layer sandwich paper (Tant-tissue-Unryu).
Later, I also designed a Kotlinconf Logo in origami.
