I've always been fascinated by the idea of hiding and finding things. Aside from Hide-and-Go-Seek and Sardines, one of my favorite games growing up was
Lego Treasure Quest, the object of which was to hide cardboard keys in various rooms. The treasure chest base would tell you which room to search for a key in, and once you found a key in all six rooms you won. Very fun!
With this in mind, my fascination with guerilla art makes a little more sense.
Let me give you a definition of guerilla art: when an artist leaves an artwork in a public place for others to enjoy and/or take. The notion that I am leaving something that someone will eventually find and hopefully enjoy is one of the things that draws me to guerilla art. Another aspect of the appeal for the artist is that you can create an atmosphere, set a mood, and influence someone's day for good. Wouldn't you like to turn the corner and unexpectedly see a framed painting randomly hanging from a brick store facade (with removable Command hooks, of course)? Or how about coming across a beautifully chalked sidewalk? I know those things would make my day, and that's the type of thing I want to do for others.
