Artworks that employ transformation usually strike me as the most interesting.  One of my favorite artists, Katharina Grosse, creates large scale installations filled with vibrant color against natural mediums, objects and outdoor spaces.

This piece below is one of the many works she has created over the years.

However, I am most excited about her latest work, Psychylustro, a piece for the City of Philadelphia Mural Arts Program.  

The sharp contrast of the pink against the weathering building references common graffiti as well as the natural reclamation of the discarded earth by flora.

Perhaps the most intriguing part of this piece is its temporariness.  The paint she used doesn’t bring harm to the environment and eventually will disappear after it is on display.  The most accessible way to see her piece is by train, which leaves you with a very short, temporary view, just like the piece itself.  So if you are in the area, be sure to catch a look at this piece, because once Katharina stops maintaining it, the piece will be gone.
