A dice, lost inside a old style wooden school bench. The picture is shot from inside the bench drawer. A shaft of light falls on the dice from a slit on the top right. The dice is in front of the camera, displaying the score six on its only visible face. The wooden interior of the bench is raw and dusty, with paint streaks and tone variations on the wood. Five circular spots of light, coming from a hole not visible on the picture (the ink pot well lit by several light sources in the room), are marking the wooden floor where lies the dice.

TIL \xrightarrow and \xRightarrow in the #mathtools #latex package. This produce a nice arrow, pointing to the right with text written on the top (with braced argument) or bottom (with bracket argument) of the arrow. The arrow length is adapted to the text length.
