I have made many projects, some of which are incomplete. In the case of Free Hero Mesh (a puzzle game engine, like MESH:Hero but many enhancements; in fact I originally wrote it because I wanted to play Hero Hearts on Linux) maybe it is too late (it is ready for use although improvements may be made in future; some features are incomplete so far). I also had incomplete (and not working yet) such as Pokemon Text Battle (supposed to be a Pokemon battle simulator in C, with a C API (do you have some ideas about how this API could work? I have some ideas but I am not sure that they are very good (I partially wrote the .h file so far), so I want to ensure to improve it before it is implemented); there are some features I had wanted to implement that other battle simulators lack, including a telnet-based implementation), and a currently unnamed operating system design (I have many ideas but no name yet; this includes a capability-based system with proxy capabilities, a hypertext file system with no file names and no directory structures (file streams can contain links to other files though, both to a fixed version and do a varying version are possible), a common file format for most types of data which can even be (text, tables, time series, and many others), integrated command-line with GUI, accessibility and multilingualization, non-Unicode, and many other ideas; I have written some about it on Usenet).
