Backgrounds for my beardies tank??

Okay so right now my background for my tank is a styrofoam wall that came with my exo-terra. However, I noticed that my beardie likes to claw at it a lot and bit and pieces of the styrofoam are coming off. I don't want this to cause impaction and it makes a mess in the enclosure. I want to get rid of it and add a stick on background that covers three sides of the enclosure. I can't seem to find a good design for my tank for a good price. My tank is an exo-terra 36x18x18. I kind of want a desert background with a little bit of green because I also have a tree decor that I want to blend it. Oh also, should I even get rid of the styrofoam background? He likes to climb it a lot but often climbs all the way to the top and even to the lid of the tank. He like hands upside down. I take him out to stop but he keeps doing it.
I love the background she has but can't seem to find it anywhere!!

I have the same tank and got rid of that foam almost immediately. It took up too much space. I replaced it with a photo background using pictures I took in Australia. I just had the local print shop print them out in large format to the right size.
