our eyes have some tendency to believe that
randomness <=> equiprobability.
And by contraposition, non-equiprobability <=> non-randomness.

quite easy to see "a posteriori" patterns in
non-equiprobable, but alas perfectly random, samples.

In french, in 2D this effect is sometimes called "effet rateau".
