Reykjavik-based designer Sruli Recht has created a carbon dater pen, which is a black diamond-tipped pen that writes on glass. Most would see this as just an expensive ($1,067.00) carbon dater pen but to a graffiti artist, this would open up new canvases such as glass store windows, bottles, or car windshields. I'm not saying I would write on these things if I had this pen, I'm just saying this is something a street graffiti artist might do.
