I try to keep my home screen wallpapers school related: this is what I found when searching for "photosynthesis".
My desktop background cycles every minute, it is mainly TV shows along with other things that i enjoy These are all of them, obviously they much bigger than this.
My wallpaper is actually a slideshow of my 'warm aesthetic' folder, in tile-fill, so I can't share those ones, but my lock screen wallpaper of my desktop is this photo, but larger of course: I hope what I said makes sense. Edit: a collage of the slideshow images.
I've got multiple, but this are the ones I was able to find in my folder: I do aslso have some with a lot more nature on it, and about no castle, but at all are photo's like this
Well... When I got my PC it has Vista pre-installed and for some reason I didn't mind the yellow/green-ish default wallpaper all that much, so I used that. Eventually I bought Win7 Professional and upgraded, but that posted a major problem because the Win7 default logo gave me plain out headaches. The blue/white combo was way too noisy for me. But because I liked the blue'ish approach I decided to search for something which would be much better on the eyes, eventually I ended up in an Anime section and yah, the rest is history as they say. I think I've been using this one for over 8 years now It matches the blue-tinted taskbar in Win7 really well
This thread also made me realise I probably don't have my home screen pages set up in the most convenient way... I don't ever use Photo Booth, and I use Contacts and Facetime less than once a month. I'm used to every app's location, though, so I don't really feel like changing anything around.
