Hope I'm not covering old ground, but I'm wondering whether any one is
interested and would like to comment on Marr's idea of vision involving a
primal sketch at a basic level. I'm interested, despite much ignorance here,
because it links to the image schemas of Lakoff and co..
Here's an interesting approach to developing the idea for computers, (which
also happens to be well-illustrated unlike many expositions of Marr), by
Cheng-en Guo, Song-Chun Zhu, and Ying Nian Wu
Departments of Statistics and Computer Science

And what particularly appealed to me, again in connection with image
schemas, is the idea of a dictionary of image primitives being used for the
sketching. I like this because there seems to me to be two levels to schemas
both in the brain and in our cultural forms of graphics/icons/schemas - a
more detailed figure-outline level and an abstract level where any movement
can be reduced to an arrow, and any shape to a line or circle.
