This is absolutely possible. How, do you ask? First off, take a musical mind. Some musically inclined people can think of over 20 instruments simultaneously (I myself can do this). Sure it's a musical thought, but a thought is a thought.

Now taking this is to account, replace an auditory sense with a visual sense. Perhaps, even both at once.


It would be very interesting to see a powerful LD-er take on this challenge...
