I happened to see an article from April 12th (link from Chosun Ilbo is omitted). It's MemPalace, which "Milla Jovovich," the lead actress of the "Resident Evil" series we all know well, directly designed the concept and structure for and participated in coding. It has an impressive 49.3k GitHub stars. Looking at the contributor list, she proudly ranks 4th. Of course, she says that the actual developer led the coding, but isn't this amazing? They say there are many hidden talented people in the world.
I feel ashamed that I have never contributed to open source.
