Beautiful visualization | Sum of first n Hex numbers = n^3 | animation

In this animation I'll show why the sum of first n Hex numbers is equal to nxnxn. Hex number (or centered hexagonal number) is just a number of dots that surround the center dot in a hexagonal lattice.
Hope you like this video.
