These bouncy Olymoic pictograms for the upcoming Rio 2016 games were designed in-house, by the Rio 2016 design team.
They were ultimately influenced from the custom made Olympic typeface which was designed by Dalton Maag, which was itself based on the original Rio Olympic logo.
Although not a style I’m particularly fond of, they do, however, work perfectly within the entire Rio brand identity. They look and feel perfectly at home, and each pictogram seems to clearly represent each sport etc.
From the Rio 2016 website:” Sport pictograms are graphic icons facilitating the visual identification of each sport and are a Games tradition. In 2016, each Olympic and Paralympic sport will be represented by a unique pictogram for the first time. The Rio Games have 64 pictograms – 41 Olympic and 23 Paralympic – and you can check them out below.
