I've really Myst you

It's not often I can actually read what the graffiti says, but in this first case, I think I can. Anybody who is a fan of puzzling video games will know Myst as well. The second piece of art is an interesting one as well. The third and fourth aren't the greatest, but they all have something interesting about them. I always find it interesting to see how the art degrades over time. Myst is obviously very fresh, in fact, it is dated 2006.
