There's nothing new about using pictograms to represent Olympic Games sport disciplines, with the London 1948 Games being the first. Since then, the use of pictograms has become increasingly popular and has taken on an extended role beyond such things as navigation and ticketing, to include advertising and licensed merchandise. Accordingly, the Sochi 2014 Organizing Committee has released a collection of 22 images of Olympic disciplines for use in the upcoming Winter Games. These apparently were adapted from those employed for the 1980 Moscow Olympics, with the result being designs that the Committee states are "powerful symbols of unity from the past and resonate strongly with most Russians."
While that's an important point, the solid-colored pictograms may seem to lack a certain graphical rigor to the Western eye. More successful are the "patchwork" versions, which are in phase with the overall graphical look of the Sochi Games and employ a combination of 16 ornaments of the most famous national crafts in Russia.
