Audio-visual synesthetes

Do you hear sound corresponding to movement, even when you know that it must be just in your head (i.e., watching a television with the sound muted)? You may have a rather interesting form of synesthesia.

Check out this video for an interesting demonstration.

Synesthesia is a very strange but fascinating condition, one that I would like to spend time studying as part of a cognitive psych/neuroscience degree. Crossed sensory pathways...a very provocative idea.
