The LHCb collaboration has just released the LHCb Ntupling Service: a web service for on-demand production and publishing of custom LHCb open data. This provides the public access to both Run I (2010-2012), and for the first time, Run II (2015-2018)  data of proton-proton collisions collected by LHCb. This amounts to over 4 PB of data to explore! The image displays an event recorded during Run II. Particles identified as different particles are shown in different colours.
