Kolam (Tamil:Beauty etc) is a ecorative design drawn in a variety of sandpainting using rice powder by female members of the family in front of their home, especially near the threshold. It is widely practised by Hindus in South India. A Kolam is a sort of painted prayer -- a line drawing composed of curved loops, drawn around a grid pattern of dots. They are generally symmetric. They, especially old/classical ones are a single cycle or circuit(in graph theory) or multi cycles and also similar with Celtic knot patterns.
