This document describes a LEGO SERIOUSPLAY workshop held at the Joomla World Conference 2015 to discuss the future of the Joomla community. Participants were led through exercises using LEGO bricks to build models representing themselves, the Joomla content management system, and their visions for the Joomla community in 10 years. They then shared their individual models and collaborated in groups to build a joint representation and commit to actions to make their shared vision a reality. The goal was to engage participants and facilitate creative thinking about the future of the Joomla community through symbolic play and model building.
