The Rio 2016 paralympic games logo, created by Tátil Design, is most likely the first multi-sensory brand ever made, which was designed in full 3D, adding a whole new level of accessibility, as it can be interpreted by anyone, regardless of a disability.
Excerpt from Design Boom:
The rio 2016 paralympic symbol is accessible to all individuals, as the shape of the logo is one which IPC and Tátil Design believe honors the multisensory necessity of a world comprised of capable people with varied refinements in sense.
