Before I got a Mac, I had Photoshop installed on my PC. This was in high school, and I think I could have become a beast photo editor. Alas.
I don't currently have a copy of Photoshop, but I figured I must have something already installed that can at least do some basic collage work. Enter Microsoft Word. I think a child could have put the above file together, but I am happy that I've found something to play with and learn.
Side note: I really do want all those things.
