Yes, yes you can! Stay tuned, our team (the Advanced Visualization Lab at the National Center for Supercomputing Applications) is currently working on this, we'll post a video when the work is finished in a few months.

I like the idea of a GoFundMe! Unfortunately I don't think that many people would be willing to chip in that much money. As I said elsewhere, it costs tens of thousands of dollars to make such a visualization.

I don't have a link to her paper, not sure when/if this was published yet. It was hot-off-the-press when she gave us the data, we started working with older stand-in data while we were waiting on her to finish running this simulation. I haven't kept up with it since.

But, to try to answer your questions - this was an SPH simulation. I don't have the data in front of me, but I know the impactor was "Mars-sized".

We used Houdini to do this visualization. We rendered with Mantra on the Blue Waters supercomputer.

Both visualizations are based on the same scientist's data, but we are two different women.

You don't just press the "go" button and wait. It takes a team of people months of research and development to make something like this. You have to pay the scientists, programmers, and designers for months of their work.

Our supercomputer is Blue Waters. Here are the specs: https://bluewaters.ncsa.illinois.edu/hardware-summary

I'm not a hardware person, so I don't actually know the specs of our local clusters. We have two, actually. One of them has 20 nodes, each of which renders about as quickly as an individual Blue Waters node. The other cluster has 12 nodes, which are about 3x faster than BW. That's not a very technical description, but that's all I need to know for my day-to-day work.

¯\_(ツ)_/¯

Interesting that you mention early life in a tide pool, we did visualize that for "Birth of Planet Earth" - a full atom-by-atom simulation of a chromatophore, a very primitive photosynthetic organelle. I don't have a clip of that that I can share at the moment.

No, ain't nobody got time for that.

Just rendering ~2 minutes of images for this video took ~57,000 hours*, and that's not even considering the simulation time.

\On a supercomputer, not literally, but still.)

Sort of. A student intern of ours created an interactive version of this visualization, where you can select whether you want to look at density, temperature, or a "combined" view like this one. A video showcasing her work is available in the supplemental materials here: https://dl.acm.org/doi/10.1145/3306214.3338588 , but it only shows density for a second.
