The incredibly lifelike computer simulations of snow and water seen in effects-heavy Hollywood blockbusters—and even video games—require a significant amount of computing power. It's not uncommon for a single frame of a movie to require days to render, and these days visual effect studios have more computing power than Nasa.
These simulations are light years from what you'll see at the movies, but are no less impressive given even a semi-capable calculator could handle them. And it ensures that future attempts at converting full-length movies into ASCII art will be all the more realistic. [YouTube via The Awesomer]
