My husband's been making pixel art as part of the #Septembit challenge for the last 6 years (he also did part of 2020 in retrospect and I've asked him to think about doing the rest this year).
Sometimes he makes them gifs. It's brought him a lot of joy and now he sometimes makes pixel art for his students too. You can see it all here: https://micahtillman.com/pixel-art/
