Centrosomes, the microtubule nucleation centre of most cells, consist of two centrioles surrounded by pericentriolar material (PCM). The PCM has been considered as amorphous but, using subdiffraction fluorescence microscopy approaches, Agard and colleagues now reveal the organized structure of the PCM of Drosophila centrosomes.
