         | This looks super fun.

         | Moonshot[1] is another similar game, and a bit more polished.
         | It was abandoned, unfortunately, but it's fun for a few
         | minutes.
         | 
         | I just noticed there's Orbit Outlaws[2] from the same
         | developer, which builds on the same concept (for better or
         | worse), but is also abandoned.

         | The desktop marketshare of the various platforms hasn't
         | fundamentally shifted since then. Mobile was all additive, and
         | Microsoft lost it. But Mac and Linux remain roughly where they
         | were.

           | Yes, I don't question the usefulness of the project by any

           | am still curious about simulations.
           | 
           | The graph on the chart I shared suggests that the peak of
           | contributions was a couple of years ago, with occasional
           | changes since then. This doesn't make much sense to me, as
           | the rendering quality looks great (at least in the videos--
           | I'll try the software a bit later), and it's head and
           | shoulders above what the scientific community is currently
           | using.

             | You can't imagine that someone working on something like

             | must a piece of software / code constantly be changing?
             | What's your specific concern? You're making a very strong
             | claim that the "project has stalled" without any real
             | evidence. Furthermore, the project "stalling" makes it
             | less... what, exactly?

             | I don't think that it's fair to compare the rendering to
             | what is currently in use in the scientific community, for
             | two main reasons:
             | 
             | The first is that different types of rendering have
             | different uses; typically in scientific visualization this
             | is broken down into essentially "viz for self, viz for
             | peers, viz for others" and oftentimes the most well-used
             | rendering engines are targeted squarely at the first and
             | second categories. The visual language in those categories
             | is qualitatively different than that used for more "outward
             | facing" renderings.
             | 
             | The second reason is that I disagree with your assertion
             | about the quality of the visualization techniques in use
             | within science. There are some truly spectacular
             | visualization engines for cosmology and galaxy formation --
             | just to pick two examples off the top of my head, the work
             | done by Ralf Kaehler or that by Dylan Nelson. (There are
             | _many_ really good examples, however, and I feel guilty not
             | mentioning more.)
             | 
             | As I said in another, rather terse and unelaborated
             | comment, though, this is really, really impressive work. I
             | think it's important that in praising it, however, we don't
             | discount the work that's been done elsewhere. This need not
             | be zero-sum.

         | I dunno, I have active hobby projects that go weeks to months
