We've just started a new open source project, Theta Tools, and are looking for contributions!
Theta Tools is a collection of ready-to-use HTML based components that you can use in your projects. The project opened a few days ago, so there aren't many components yet, but my aim is, that people will contribute their components to the project. Any and all contributions are welcome, and your contributions will count towards Hacktoberfest!
You can find everything you need to use our components, and contribute to the project at our website
