  I love your comment on the projection math and it reminds me so much of the projects I’d work on growing up. I think when we’re young excited programmers we just want to build cool things, but we don’t know any of the underlying principles necessarily, so we just build it with whatever we have in the toolbox. Especially back then when finding information about how to do things “the right way” was a lot harder, I’d think about what I wanted to accomplish and then immediately just try my darndest to get it to work in whatever hacky way I could come up with. I’d always be flabbergasted a year later in school when I realized if I had known this math or physics principle my solution to that programming problem would have taken me 15 minutes instead of four days. I wish I still had some of that old code to look back on, but alas those hard drives are long gone.

  Wow that's really cool. I liked the structure you added to the Martian landscape.

  It was funny to wake up and see this on HN, as I was watching something DOS and 3D-related on Bisqwit's channel last night.

  Nice work! Reminds me of the type of projects that used to be posted as "Image of the Day" on Flipcode.
