 First one, then two, then three, then four figures, dancers or mime artistes, dressed in coloured djellabas (white, yellow, blue and red) appear one after another to scurry along the sides and across the diagonals of a square, shuffling in strict rhythm to a rapid percussion beat.Each figure then departs in the order in which he appeared, leaving another to recommence the sequence … Strikingly all of them avoid the centre which is clearly visible in the middle of the square.
