Have you ever had to read text from a cheap dot-matrix printer which is not aligned quite right, so that the tops of the letters are either darker or lighter than the bottoms?

Now with IrritationOne and IrritationTwo you can relive that experience even though you no longer use a dot-matrixed printer. IrritationOne has dark tops and fading bottoms, while IrritationTwo has the opposite.

Naturally both are monospaced.
