Rangoli Machine

Created on 04 Nov 2017

Those colored sand pictures are nice, but don't they take forever to make?

Rangoli is an intricate pattern created with sand (or other materials) traditionally drawn during Diwali or other Hindu festivals. Drawing a rangoli can take quite a while. We will build a device to draw rangoli using colored sand.
