Oliver West

Some of this guys ideas can be pretty interesting, especially, but certainly not exclusively aimed at those with learning difficulties, his ideas on visual thinking could be employed perhaps to help us understand and push ourselves to improve.

He, incidentally is an artist, print-maker and university lecturer but you can see that stuff on the site. I came across him by looking at some of his YouTube videos.
I should mention that he himself is chronically dyslexic (why did they make that word so hard to spell?!?!).And here is something a little more nostalgic featuring Kermit the frog to show you that visual thinking is not necessarily a new idea.
