The cursor icon in the image is a blue cube from the popular game Geometry Dash. It is animated and appears in two forms - the cube form and the UFO form. The cube form, which is the default form, is represented by a blue cube with a black border. The UFO form is also blue with a black border but has a unique design. The cursor icon adds a dynamic and playful element to the user interface, fitting in with the theme of the game.
