Dreamlike animation illustrating Fibonacci sequence, Golden Ratio, and more

In "Nature by Numbers," filmmaker Cristobal Vila presents a series of animations illustrating various mathematic principles, beginning with a breathtaking animation of the Fibonacci sequence. Then it moves on to the Golden and Angle Ratios, the Delaunay Triangulation and Voronoi Tessellations. This would be math-class gold, and it's awfully sweet even if math class is years behind you.
