A quick not so clean try of Mohanaji's rangoli on the wall, with colored chalk! We had fun trying this pattern both on the wall and the paper. The picture isn't clear enough since I had used pastel colored chalk on light colored wall.
I've added two levels other than what's found on Mohanaji's pattern. Here is the level of complexity:
n = 0, no of lines = 0, no of dots = 1
n = 1, no of lines = 1 (1 green), no of dots = 5
n = 2, no of lines = 5 (4 green, 1 pink), no of dots = 25
n = 3, no of lines = 9 (4 green, 4 pink, 1 blue), no of dots = 61
n = 4, no of lines = 13 (4 green, 4 pink, 4 blue, 1 red), no of dots = 113
n = 5, no of lines = 17 (4 green, 4 pink, 4 blue, 4 orange, 1 purple), no of dots = 181
n = 6, no of lines=21 (4 green, 4 pink, 4 blue, 4 orange, 4 purple , 1 light green) no of dots = 265
