This article talks about the rising of Braille street art started by Austin Seraphin and Sonia Petruse. The idea of Braille street art was first conceived by these two due to the lack of braille found around us: "I don't encounter that much Braille in public - it's not like you go around feeling surfaces. The Braille I encounter the most is at my elevator here, and there's some at ATMs,". This article brings to light the definition of beauty and art, and whether only those who can see art can appreciate art.

I've often thought about sense perception and whether or not each of us view the world the same way. This article talks about color perception and it also talks about a monkey experiment which "suggests color perception emerges in our brains in response to our experiences of the outside world, but that this process ensues according to no predetermined pattern."
