One kilometer world
During the second national lockdown in France, one was allowed to walk in the radius of one kilometer from their residency and restricted to one hour. I made myself the map of my new world for several weeks and walked around the whole circle in one go. The whole circumference of the 1km radius allowance was exactly 7,37km. Afterwards I went for a walk almost everyday trying to discover all the possible streets and alleys filling up this circle.
