thingiverse

A spatial challenge and fidget toy for all ages: Take a tile with one rail and one slot, then connect it to a set of identical tiles. Questions to Ponder: 1. What is the minimum number of tiles needed to form a solid perimeter? 2. Are there shapes beyond the square that can be created? 3. How many tiles are required for 8, 16, and more configurations? 4. Can this challenge be expressed in an algebraic equation?
