Show HN: [WebGL Demo] Interactive Mesh Deformation in JavaScript

In case the demo doesn't run, I have prepared a video of it here(https://www.youtube.com/watch?v=1bykYClXkRg)

This is a demo that implements laplacian deformation in Javascript. Laplacian deformation is a technique that allows you to deform an arbitrary mesh as if it were a cloth-like material. In the demo, you can grab handles on the mesh, and drag them. The vertices of the rest of the mesh are then smoothly updated, resulting in a deformation. The deformations produced by this technique tend to look natural, since the general shape of the mesh is preserved. This kind of technique is useful in 3D-modeling software.
