[Blindmath] First attempt at an SWT/SVG based drawing program

Wed Aug 31 13:18:09 UTC 2011

Amanda,

What an interesting combination of tools.  I've read about The vOICe 
before but dismissed it as too "noisy" to truly visualize anything with it.

Has your experience been different?  Are you genuinely able to make 
sense of new drawings, pictures, or physical scenes with it?

Have you tried it in a mobile situation, such as walking about campus?

Looking forward to hearing your experiences,

Ben
