What is this?

Icon a Day is a daily design challenge. Every day I post a brief for a made-up app, company or brand, and anyone can design an icon for it and share it. Use paper, a design tool or the editor, whatever you like. I started it because I noticed that with AI I was more productive, but I was thinking less, being less creative and doing less with my own hands. Creativity is like any muscle: if I don't train it, it atrophies. So this is my daily workout, and you're welcome to join. Vote for your favourites and the most-voted icon wins the day.
