PicoC is a very small C interpreter for scripting. It was originally written for scripting a UAV's on-board flight system and it's also very suitable for other robotic, embedded and non-embedded applications too.

The core C source code is around 3500 lines of code. It's not intended to be a complete implementation of ISO C but it does pretty much everything you need. When compiled it only takes a few k of code space and is also very sparing of data space. This means it can work well in small embedded devices. It's also a fun example of how to create a very small language implementation while still keeping the code readable.

picoc is still under development but is approaching a 1.0 release. Version 0.93 is a beta version which is close to feature-complete. It's been tested on x86-32, x86-64, powerpc, arm, ultrasparc, HP-PA and blackfin processors and is easy to port to new targets.
