Since getting my computer, I'd just been using the default background. I felt like putting my own on, and kinda thought "Maybe my 'rex", or rather the texture I painted for this rex, but you get the idea.
While I was doing that I ended up thinking about making a batch of these. A few days later (Since messing with settings halfway through the batch making + some complications) I have this ^^

It's pretty simple, but anyone who'd want to take a look here it be!. Portrait versions for mobiles too, because why not.
File is 430mb, using 7zip.
