The mark consists of the letters "iN", with the letter "i" in lower case and the letter "N" in upper case, followed by the mathematical integral symbol, followed by the letter "X" in upper case, all in stylized format. The letters "iN" and the mathematical integral symbol are displayed in white, with a grey shadow bordering the interior right side and bottom of these elements of the mark. The letter "X" is displayed in red, with a white border on the interior left side and top of this letter. The letters and symbol are superimposed against a black, rounded rectangle, which is tilted slight to the right, and the upper and lower ends of the mathematical integral symbol extend slightly beyond the bounds of the rectangle. Within the rectangle, the letters and symbol are bounded by a white border to the left and top of these elements. The rectangle is bounded by a grey border, broken by the extended elements of the mathematical integral symbol.
