Urban Readymades

This evening I was talking with artist Ron Sluik (formerly member of video art/noise/punk collective Auto Awac in the Netherlands) and he mentioned to me the notion of "urban readymades" - i.e. things you can encounter in the streets that can be recontextualised as art objects according to how one perceives them. The idea resonates for me, since I've been doing this for quite a long time, as have many others I know. There  are websites devoted to urban readymades and urban readymades though at this moment they are apparently under reconstruction so there is not as much to see as there might be. But the internet is presumably full of stuff that could fit this category anyway, not to mention all our personal photo collections. But to cut a long story short, "Urban Readymades" seems like a perfect BUU theme.
