What if there were a low-cost, widely available visualization app that allowed you to explore and interact with your data in 3D? While building Minecraft mods with his kids, Pat Patterson realized that he could generate whole worlds from data in a Salesforce org, use push notifications to modify the world in real-time, and even have actions in the virtual world generate API calls to update that data. Join us as Pat explains the workings of Forcecraft, and argues that great things happen when developers cut loose and have some fun!
