How did I go from this

to this?

With the
Wonderland World Builder of course.
The world builder is a simple browser-based application that makes it possible to create Wonderland worlds. Using a simple drag-and-drop interface, one simply drags tiles onto a 2D grid and positions them. After saving the world, it can be easily accessed from the Wonderland client.
The software itself comes with a set of very functional tiles. It is also possible to create tiles using Blender and the Gimp.
The world builder has been discussed at the
Wonderblog.
It would be disingenuous to say that it was easy to set everything up on my development machine. However, the
Wonderland Community is refreshingly fast at providing solutions when one gets stuck.
