Wow, that sounds like a dream playground—mixing origami precision with the spontaneity of city streets. I’d love to help you fold those recycled sheets into a maze of modular buildings that you can reconfigure whenever you feel like a new skyline.

Sure thing, let’s start simple and keep everything tidy so you can swap pieces fast. Pick a sturdy recycled paper—old newspapers or cardstock works. Cut a 10 cm square; fold it in half, crease, then unfold. On one side, score a line 2 cm from the edge so it folds into a small wall. Fold the other side the same way, but 3 cm from the edge—this will be the roof. Glue the corners where the walls meet the roof, keeping the edges crisp. Repeat a few times, then stack a couple of bricks together: glue the open side of one brick to the back of another. You’ll have a basic modular block that can link horizontally or stack vertically. When you need a new district, just pull a brick out, tweak its shape slightly, and re‑glue. That keeps the flow smooth and lets creativity run wild. Let me know if you need more detail on the scoring or alternative shapes!
