In an attempt to encourage the creation of more pony visual novels, Taivastiuku decided to create a web-based tool for that purpose and called it PoniPoni. It's still in a fairly early state, mind you, and the average person probably won't give this more than a passing glance at the moment, but I get the impression that if this ever gets anywhere it could become a rather useful tool for folks wanting to whip together a quick VN. Perhaps more developers would be attracted to the project if the source code were to be released on GitHub or something, I dunno.
