For those for whom that statement may be enigmatic, let me explain that Debian is a Linux distribution, and Buster is to be the name of the next version, Buster being a character from the movie Toy Story, after whose characters Debian versions are named.
With that out of the way, here are three of my favourite wallpapers from the Buster artwork proposals page on the Debian Wiki.
Debian users may notice that Juliette Taka Belin's artwork was chosen for the two previous versions of Debian, Jessie and Stretch.
Moonlight is my favourite, as her proposal for Stretch was previously.
Good luck Juliette Taka Belin for three in a row!
