This is my setup for my BRB, step by step..
Please remember, I dont know what alle the materials Ive used is called in english, sorry bout that..
This project took me 1-2 weeks to do from the old BCI setup..
First I cleaned it up, removing some of the background
Two bottles of foam to make some structure for the new background
The next 5 pics is how I draw the lines for how I wanted it to look like

This is some hard work, putting some brown sticky mass on to the structure and then some "dirt" (Dont know how to say it, it isn't regular dirt) on to the sticky mass, I do this a little piece of the time, so it dont dry up..

Use your fingers to get it right.
If its going on some big surface, use a DVD cover to even it out..
This is the same thing done, for more plants..

To make the light less annoying, I put some of the brown sticky thing on the lamp
Under the bark theres a heatmat connected to a thermostat, on the picture the heat isn't turned up yet, therefore showing only roomtemperature
This is what it look like at night
There has been a few changes along the way and this is how it looks like at the moment:
Im sorry about the lack of information about the materials and my incorrect spelling
Enjoy..
