It started out as an idea to change the original Dutch Station Set graphics into island-style graphics. But it grew out to a lot more

The first mentioning of this idea can be found here: http://www.tt-forums.net/viewtopic.php? ... 0#p1059887
This also has all the discussions until the first release (v0.1)

0.8 is available on the ingame download (Bananas).
