I have a few sexy background pics but recently I have now started using my desktop background in an occupational manner (See my picture below). I do not think many people know this but you can divide your desktop in a picture based quadrant in Microsoft word.
You can set thumbnails of images to represent tasks and drag the thumbnails when you are done. Also you can put images of things that you tend to forget. For example if you forget to set an alarm to stretch every 1 hour you can put this on your desktop screensaver or remind yourself to take certain medications at certain time. Simirarly you can also do something similar for the windows login screen so that you can remind yourself to get certain things ready before you login in to your computer in the morning such as a diary or making sure your shower and what-not (although most people remember - these things can get overlooked when you are busy and this is a good way of doing things.).
Having sexy anime babes on desktops is amazing but it is amazing that people to not really use their desktops or login screen's in an productivity oriented manner despite many exotic desktop background being amazingly well drawn.
The second image is my login screen which reminds me to make sure that I check the charge of my phone and make my bed in the morning as well as do thinks like tick off my physical calendar and check things like my google calendar. I also use them at work sometimes to remind me to do thinks like unlock certain cupboards or doors before loggining in and starting work.
I hope that it is okay to post and share these, in case it helps someone else.
