I went to @offline yesterday. There were presentations about
- Bicycle wheel LED patterns generated with rust running on a raspberry pi mounted on a piece of cardboard
- A prototype of a musical instrument inspired by Alexander Bogdanov's utopian ideas about blood transfusion, eternal life and a communist society on Mars
- A beautiful film documenting the VR Chat subculture in Korea.
Among other things. Really enjoyed it and put Red Star on my reading list. https://en.wikipedia.org/wiki/Red_Star_(novel)
