I'm making an HID translation dongle.

In programming mode, its a flash drive you can put LUA scripts on.

In run mode, you can select a lua script to run. Lua scripts can take HID input and produce HID output.

All open source, hardware and software: https://github.com/cedarhacks/ReMapper

It can do things like keyboard -> joystick mapping, key logging, macros, mouse wiggling etc etc
