Two “Calebasses”(calabashes) are joined by a motor and move autonomously on the pavement and soils through Dakar city to meet moving cars, pedestrians and horses on its way. Sometimes individuals stop and watch others ignore and pass. A spontaneous intervention that shows a known object moving unpredictably from one side to the other. The sounds of the environment are merged with the buzzing sound of the motor and the crunching sound of sand and stones under the rolling “Calebasses”.
