Israel and Palestine are essentially graffiti states. The Israelis, West Bankers and Gazans love expressing their ideas on the wall.
I will put some pictures on my blog. Some of the graffiti have cultural references, some require knowledge of certain political context. By no means do I understand a small part of what I need to know to break through complicated ideologies and sophisticated designs of some graffiti gods. Oh, and some graffiti, believe it or not, have no idea behind them at all.
