Celebrating the event displays: Visualising the data is really powerful and shows how beautiful the experiment can be. At the same time, it can also point to the brutal truth because it can tell you something that does not work as expected! 

Ever-increasing luminosity, advances in computing, and the creativity of the LHC experiments are driving event displays to new levels of sophistication for physics and outreach activities. The new ALICE event display provides extremely crisp and detailed views of the physics processes in the detectors. The picture shows a single lead–lead collision at 5.36 TeV per nucleon pair measured with ALICE, the fully reconstructed tracks are plotted to achieve the most efficient visualisation.
