  There's some nice bindings for SDL that's rather well-maintained: https://github.com/AngryLawyer/rust-sdl2 https://github.com/AngryLawyer/rust-sdl2

  Things are moving fast. I'm not sure what you need specifically, but piston[1,2] is probably what to look at and maybe more specifically image[3] or conrod[4] [1]:http://www.piston.rs http://www.piston.rs [2]:http://www.reddit.com/r/rust/comments/28srso/piston_game_engine_notice_on_progress/ http://www.reddit.com/r/rust/comments/28srso/piston_game_eng...

    If you try the piston getting started example on Windows (the spinning square), change the freetype name to "libfreetype.a" and put it in the 1.0 path: C:\Program Files\Rust stable 1.0\bin\rustlib\x86_64-pc-windows-gnu\lib Other than that it works.

  Depends on the 2d graphics you want. There are Rust bindings for GTK+3 if you want a toolkit, or bindings for Cairo if you want raw 2d graphics.

Just sent a couple of pull requests to make this run on stable Rust 1.0.0 (using swaps instead of the unstable drain feature), and to clarify that production rules shouldn't be able to mutate their environment (they should be pure functions). Great library, and a good introduction to how Rust's typing can make algorithm implementations a pleasure to read in code! EDIT: Links for the curious: https://github.com/atheriel/lsystem/pull/2 https://github.com/atheriel/lsystem/pull/2 https://github.com/atheriel/lsystem/pull/3 https://github.com/atheriel/lsystem/pull/3

Very cool, L-systems are fascinating. As an apropos, there was actually released a Rust implementation of Turtle graphics recently: https://github.com/Kingdread/Rurtle https://github.com/Kingdread/Rurtle
