Kolams (or kolem) are large, intricate apotropaic figures representing various Hindu deities and auspicious signs. Kolams are typically drawn on altars and outside of doorways. Similar to the veves of Vodoun, they are created on the ground with white powder (usually ground rice or powdered stone). They must be drawn unicursally (in one continuous line), so it is considered a skill to be able to complete one without pause. A colorful variant called Rangoli are drawn with powdered pigments or chalk.
