I think that you are thinking back-words... this is really the easiest way!!
(did it in high school as a freshman)
The Idea is not to map out the traces but the gaps... If you can dunk a
donut you can do this :)

Nanoscience?), and (I THINK it was in that program, anyhow), they showed
this lab where they had hooked up something to this woman and used it
instead of the mouse, and she could actually move the cursor by thinking
about it. If it didn't work, she said that getting angry didn't help, so it
was difficult to stay calm.
Anyhow, it's still in development, but MAN, was that COOL!
Peace out!
