Merry Christmas all,

I remember a really useful tool which you could access online using a browser. It had a list of different 2D materials, and displayed a phonon band structure and a stick-and-ball model of the lattice of the selected material. You could click at a point on the phonon dispersion, and it would animate the lattice model to show what the vibration looked like in real-space.

Does this tool still exist? Can anybody help me to find it again?

Thank you!

Tom
