Event displays are an excellent tool to visualise HEP events, for physicist but also for outreach. In the old days,these 3d visualisation tools were a challenge, and thus some experiments decided to use a commercial closed source back-end solution. This talk tells the story of how a little open source project of an enthusiastic game developer helped to resurrect these useful tools for two of the LEP experiments..
