The Tech Wall at the corner of Slater and Bronson is such a space.  The area gets its name from the owners of the land, namely, the Ottawa Technical High School. The work on the wall ranges from tags to full-fledged murals.  The wall is in constant renewal, and to the casual observer, it would appear that anyone’s great work is subject to being overwritten at any time.  Given the effort and beauty of some of the work, that could be seen as disrespectful or egocentric, but the fact that the wall is capable of morphing to its own undefined rhythm simply underscores the very nature of graffiti – it can’t be tamed.
