Can I make a pull request for a small UI animation?

[Thosedarnmonkeys]

Contributing.md explicitly says to ask before making pull requests, and I think this is the correct place to do that.

I've made a branch that animates the sleeping capybara when you tap it. It just redraws the sleeping Z's one by one, but I thought it was a nice little interaction.

I've never contributed to anything before and I'm new to Kotlin, so please let me know if anything is incorrect/inappropriate, and I'll happily make changes.

If someone with approval permission gives it the green light, I'll open a pull request.
