[BlindMath] What does the largest one-day drop in market value sound like?

Fri Aug 3 20:02:24 UTC 2018

Thank you so much. Why do blind people reject this so much? I keep hearing about these stupid three dimensional tactile pictures at the NFB convention. I went to one of the conventions and felt these pictures. They were not really 3-D because you could not really feel the back. It was more popped out if that makes sense. Detail was lacking, everything was all one texture, and I could not tell what anything was unless I read the caption. It annoyed me that these pictures were being considered so innovative and accessible.
