Ferdinand Cheval’s Wheelbarrow

Origin
Ferdinand Cheval was a French postman who spent thirty-three years of his life building Le Palais idéal (the "Ideal Palace") in Hauterives. The Palace is regarded as an extraordinary example of naïve art architecture, especially since he had no prior knowledge. His interest began when he tripped over an oddly shaped stone and it reminded him of a whimsical dream to construct his own castle. Promising to do just that, he collected loose rocks from his mail route for three decades, eventually carting them home by wheelbarrow to build his masterpiece at night.

Effects
Placing a material into the wheelbarrow will cause all unsecured pieces to flock towards the prime piece. Placing a scrap of iron will cause much of the metal in a junkyard to levitate and move towards the wheelbarrow, while sand will cause all nearby granules to funnel together in the user’s direction. They will follow just outside the user’s zone of preference until the original object is removed. At that point the materials will meld and coalesce together to form complicated and sturdy architectural features. While in use, the user will have the seeming compulsion to pick up any lose rock, pebble or stone they encounter along the way.
