An animation of creating a maze using a depth-first search maze generation algorithm, one of the simplest ways to generate a maze using a computer. Mazes generated in this manner have a low branching factor and contain many long corridors, which makes it good for generating mazes in video games. In these mazes, it will typically be relatively easy to find the origin point, since most paths lead to or from there, but it is hard to find the way out. Animation:

The stem is lavender, measuring 10–18 cm (3.9–7.1 in) long and 1–2 cm (0.4–0.8 in) thick. The edibility of the mushroom has not been determined, and it has been described as "much too slippery to be of value". Photo: John Kirkpatrick
