Microsoft paint is the built in art software that’s come with pretty much every version of windows (not sure who needs this introduction, but it never hurts to be thorough). It’s rudimentary, but that’s what made it so easy to start using as a kid, and what makes it so easy to play with over the years. I have many more paint drawings, but these are the ones I could find for now. I made a lot of these to pass the time at various desk jobs or in classes I should have been paying more attention to.
