2012 Olympics Logo

Devised by brand consultants Wolff Olins, the 2012 Olympics logo was hailed as "dynamic" and "vibrant" by organisers. A segment of animated footage released at the same time as the logo, caused seizures in a number of people who suffered from photosensitive epilepsy and is an example of how accessibility may affect any of us.
