MockMechanics is a sandbox building game and a mechanical/visual programming language. A bit like Minecraft, MockMechanics also uses simple blocks and graphics, as well as intuitive programming forms, to create complex interactive mechanics.

MockMechanics has a real physics engine, and you can use MockMechanics to make some very interesting things, including playable instruments, prototypes of machinery, visual representations of algorithms, games, and many other things. For example, the picture below is a Tetris game created in MockMechanics.

MockMechanics is written in clojure, so in addition to the visual programming of dragging blocks directly, you can also choose to use clojure as a scripting language to control the behavior of the work. For example, you can build a robotic arm (easy, a bit like building a Lego), and use clojure to make it pick up objects.

Overall, it’s a pretty decent sandbox building game to let your imagination and creativity run wild.

The source code of the software is now hosted on GitHub, and you can also download Windows 64-bit .exe files or .jar files from the official website (requires Java 11 and above).
