Why should this be included in the repository?
cli-visualizer is an amazing music/sound visualizer that is inspired by C.A.V.A. It has a ton more features, three different visualizers (Use Space to switch between them!) and an awesome set of configs and colour schemes. Plus it's rainbow by default. ?
It offers a lot more features and looks nicer than C.A.V.A. is capable of. Sound visualizers like this are really useful for streamers on Twitch/YouTube.
Is it Open Source (yes/no)
Yup, fully open-source and on GitHub.
How many users do you anticipate will use this software?
Likely quite a few. C.A.V.A has 882 stars on GitHub whereas cli-visualizer has 639 stars.
It's not as popular, but has more features, more configuration options and looks a lot nicer by default.
