Sand drawings

Normally, we in India arrange the dots for rangOlis using either the white rangOli powder or the wet rice flour. There is one more way of doing this. One can use the medium of sand and the dots can be arranged on the sand with fingers. Try this at home or when you go the beach. This is the method followed by some tribes in Angola. Angola, a former Portuguese colony, is in western Africa. They use their index and ring fingers to arrange the dots (see figure). After a certain number of rows are arranged, they continue this process to obtain the desired number of rows and columns.
