Bhavna Bheda of Mumbai made a 4D rangoli in over 18 hours at the IIT Bombay campus during the cultural festival Mood Indigo 2015. That is, when seen in normal view, one can view the rangoli properly, not blurred; and with 3D anaglyph – red and green glasses, one can view it in-depth; in the dark the original image of the rangoli changes and finally under UV light, the whole image looks entirely different. She used 100 shades of rangoli powder.
