I did a search to no avail so I wanted to share this with everyone. When Techspansion closed their doors they said that they had no intentions to make their apps open source. It looks like they've change their minds. VisualHub is now known as "FilmRedux" and is available on SourceForge (direct download). The other apps will be available as an open source product soon. Edit: After further investigation, that link I posted hasn't been compiled. Does anyone have link to a compiled build?
