Rust Raycaster

I am curious about the history of early computer graphics. Recently it has been raycasters, especially the screensaver I stared at for ages as a kid. I am not the only one motivated by this experience. See also Screensaver Subterfuge and Maze 95 JS.

To start writing this raycaster, I read Dmitry V. Sokolov's Tiny Raycaster tutorial to get inspired and get a head start on the algorithm. It was helpful to get some momentum, but I've found F. Permadi's Ray-Casting Tutorial for Game Development and Other Purposes (1996) to be very useful in actually understanding the math enough to write test cases.

While I'm still definitely in the prototype stage, things are coming together. I have learned a lot about writing Rust from this project. I'm not sure what I'll make out of it yet, but I hope to do something fun with it.

The color palette I'm using is Rust Gold 8. I like the atmosphere it brings.
