GNU libmicrohttpd is a small C library for embedding HTTP server functionality into other applications. It is reentrant, fast, supports HTTP 1.1, and permits listening on multiple ports. The API is simple and still powerful enough to allow programmers to use the entire HTTP feature set. SSL/TLS support is available as an option.
The Ecere SDK is a cross-platform toolkit for building software applications. It currently runs on Windows, Linux, Mac OS X (through X11), FreeBSD, and the Android OS. It should run on other Unix platforms with minor testing/tweaking. With the Ecere SDK, you can develop applications once and deploy them on all supported platforms alongside a lightweight runtime environment. It introduces eC, an object oriented language derived from and fully compatible with C, compromising neither runtime performance nor ease of use. A built-in 3D engine supporting both Direct3D and OpenGL is fully integrated.
The dyncall library project provides a clean and portable C interface to dynamically issue foreign function calls using small call kernels written in assembly. Instead of providing code for every bridged function call, which unnecessarily results in code bloat, only a modest number of instructions are used to invoke all calls.

Asqare is a simple game for Android. The screen is covered with colored sprites (squares or circles). When you align three or more in a row, all adjacent sprites of the shape and color vanish. You can only swap adjacent sprites vertically or horizontally. You can swap sprites even if it won't result in a three-or-more alignment, but that will cost you 10% of your current score. The game offers two variations on the gameplay and manages a list of current games, which you can pause and recall at any time.
