Yep, but I'd qualify that: The demo seems to show wet snow (snowball snow) only. There are a few other types that happen around here, like dry snow, and crystallized snow. Dry snow is light fluffy stuff that doesn't pack. And crystallized snow is made of what feels like little daggers, behaving almost like ball bearings. But still, their result is brilliant!
Have you seen "Frozen?" It really was a beautiful-looking film with lots of opportunities to show off the simulated snow they modeled.
