If you're nervous about riding the subway, you may want to steer clear of Alex Andreev's Moscow Underground art series, which fills the Russian subway with giant mutant cockroaches, malevolent metro conductors, and other bits of urban horror.

Andreev combines (illegally taken) photos of the Moscow Underground with other images to create portraits of gloomy horror. Some of the photos suggest the subway system (one of the oldest and deepest in the world) is a hotbed for arcane mystical activity, others seem built on urban legends of gigantic insects making their homes in the tunnels, and still others are straightforward science fiction, with the daily commute supervised by watchful robotic overlords.
