I've had a Canon EOS 550D for about 4/5 months now, and I've taken 1 image so far that is wallpaper worthy.
I took this photo in March, when I was on a roadtrip on a motorway with my camera. I was trying out long exposures, and tried a flick exposure with the back of an Audi when it was pitch black. I got this, and almost deleted it until I zoomed in and saw this.
A rope like texture. And my mind was blown. I use it as my home screen wallpaper, but it looks infinitely better on an OLED screen
I sadly do not have any more wallpaper worthy images for now, I'll add some when I get some more.
