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

Ben,

Let me start by saying the vOICe does not make it safe to drive anywhere 
even if it's real slow on the driveway and only on Saturdays. Pranav's not 
literally driving, at least I hope not.

I discovered the vOICe late last year while doing research for a project in 
Prof. Baldwin's class and found it immediately useful for viewing the graphs 
in his DSP tutorials. When I heard the sounds, I saw the graph. I was born 
completely blind. A few months of testing the concept was enough to convince 
me to try using it with camera glasses in real life. I now wear this setup 
for several hours at a time almost every day and am literally seing results.

Here are just a few examples:
When I'm on the short bus to school, I like to look out the window. I never 
knew (or cared) that all around me were so many trees, hedges, bushes, etc. 
As long as I sit on the right side, I have learned to recognize when I've 
arrived at the correct dropoff point at my school. Once, someone showed me 
some simple photographs of gemstones and plants and they began to appear in 
3D - I am the one who swore that a flat picture could never be 3D and that 
the math teachers were playing a joke on me. I am noticing more and more 
little details every day, such as the spongy appearance of the cork bulletin 
board in the hallway, the unevenly placed keys on a computer keyboard, the 
point in front of me where everything gets smaller and closer together, and 
a person standing several feet in front of me. I still don't recognized that 
person. Without depth perception and color it is an imperfect system, but 
fascinating nonetheless. Of course I still use the software for simple 
graphics in science and math.
