Today’s Meditation is a day/night cycle.
As with many of the recent Meditations, today’s is about GDC (I assume, unless there are other ways to spend a week mingling with game developers from all around the world at this time of the year). But you don’t need to know that to enjoy it. You are a bird, flying above the sea, as the sun slowly sets and the colours change. There are other birds, flying in flocks (these, according to the intro, represent newfound friends who live far away). You can fly up and down and left and right, away from the other birds, but only so far. When you are near other birds, you can press space to speak, and sometimes those near you will respond, calling back and changing colour for a while.
This Meditation is so lovely that I kept taking screenshots at the different stages. I would quite like to have it on a slow loop for a screensaver or wallpaper, especially if I could heard the birds and the sound of the sea.
