Multi-threaded (process-wise) Python imageboard software. The first of its kind, if I am not mistaken. It's not ready for the public yet, but I'm very glad to say that the project has went without problems.

In case you missed it, after a stable release is made I will be speaking with the site owners using kusaba and try to convince them to make the jump to the new software.

The front end of the software resembles wakaba more so than kusaba, with the removal of the extra features.
