The mark consists of a black rectangle shape with a stylized and slanted letter "C" appearing as a cut-out from the center of the rectangle. The black rectangle also has a triangular cut-out extending from the upper right hand corner and tapering to a point nearing the center of the letter "C." Centered in the middle of the triangular cut out is a diamond shape appearing in a gradient of red on the left to dark red on the right that extends beyond the edge of the black rectangle. The black rectangle also has a curved trapezoid cut-out extending from the lower right corner and approaching the lower exterior of the letter "C," with a small black trapezoid shaped extension of the black rectangle appearing below the trapezoid cut-out shape. The black rectangle shape appears above the capitalized word "CATAPULT" in a gradient of red on the top to dark red on the bottom above the word "CHICAGO" in black, where both words appear in stylized typeface. The color white represents background and/or transparent areas and is not part of the mark.
