The video demonstrates a geometric constraint solver program that allows users to draw simple figures by applying constraints to points. The program uses a non-linear equation solver with gradient descent to find valid solutions. The video includes demonstrations of creating a piston mechanism and exploring the algorithm behind the scenes using test algo and MATLAB.
