I updated the "How I made..." page with a text about the "impossible" template switcher.

I made a template switcher! And it has more options than light or dark. I made a third template that you can access through the switcher. And the third template has a cursor trail.

It's not perfect, but it's functional. There are some situations that will send you back to the default template, but then you can reselect the one you want.

I made a custom error 404 page. You can find it in the "just for fun" menu, or by trying to go to a page that doesn't exist.

I added a question of the day at the bottom of the pages. For now it will change based on the day of week (server time, which is CET), but that will change when I've thought of more questions. If you are signed in, I will see your user ID when you submit, which is connected to the data you entered when registering. Everyone not signed in will show with user ID 0 and I will have no idea who you are unless you write it in your response.
