I made this wallpaper for my laptop running a picture of my cat Woody through the web app on this site.

I then upscaled it through Waifu2X Caffe to clean the noise and make it a bit more....watercolory if you will.
Click the image to enlarge it and then right click, open image in new tab and save if you want this pic, or go take some nice photos and do your own!
