There is now a place event on lemmy that is a lot more laid back than the Reddit one, so I started work on a little boykisser. You can help if you want, it's current coordinates are 621,621 (iykyk) you can join here. There is no real official template, I was just somewhat following the little boykisser that was built on r/place which you can see here and otherwise just see how it develops organically.
