Tan's blind and his 'senses' only go so far as to cover obstacles in his way or the presence of people around him. Reading is another matter entirely. This would be quite the daily hassle. (for the record, I'm only picking on him because he gave up his sight willingly for someone so I feel like pointing out the consequences of his decision in a humorous light. Also he does not know braille)

Tried to make 'textures' and have some variation in my images. Think I failed :/ bah. I need more practice.
