Some of the work in the gallery is published, so you can install it rather than read about it and rebuild it yourself. Each one has a write-up here explaining how it works and what was difficult about it.
None of them has a runtime dependency: the React ones take React as a peer and nothing else. A carousel should not cost you a dependency tree, and I would rather write the maths than inherit somebody else’s. The code lives on github, and stars are always welcome.
