1. Flatten the shoebox; use its base as the platform and cut side panels into staggered rectangular backdrops.

1. Sketch NYC landmarks on black cardstock, cut out, and glue them onto backdrops in two layers. Add "windows" with metallic markers.

1. Bend cardboard strips into a ring, secure with hot glue. Line the inner edge with plastic tape for smooth motion.
2. Install a mini motor under the base, connect it to the track via a rubber band gear mechanism.

1. Assulate a train from cardboard, attach magnets to its base (repelled by track magnets for propulsion). Test motor speed.
