Blindfolded patterns

Dirk links to this interesting post where cartoonists were asked to draw their characters blindfolded (versions on the right). This Chester Gould one is pretty impressive...



What's interesting to note is where most had problems and where they were fine. Most of the linework between the blindfolded and sighted versions are the same, it's putting them all together that they had trouble with. I like this a lot since it shows that authors are using consistent patterns when drawing (as if people didn't know this), even when they can't see the page!

This all reminds me of some citation I saw that claimed blind people also use/conceive of speed lines to indicate motion, but I never fully got the chance to read up on it. Perhaps I'll hunt that one down...
