Watch a colorful cube spin to music. That's it. You can change the spin speed and background but that's it. Just a playlist. Every hour a different animal crossing song plays, except on Friday. Friday is a party day. Maybe it'll change into its own Friday playlist. For every holiday with a background, the background will start at that holiday background, but otherwise it goes to a light mode before noon, then going to dark mode after.
24 Songs were used from several animal crossing games, each named respectively to the hours they play, and funky town was also used as a song for Fridays. I don't know how to use pen to create a 3d model so I did it by hand, looks slightly janky.
