How do you remove spray paint from cement?

There is a thread about it here: http://www.thriftyfun.com/tf9154…

Soft Scrub seems to work for small amounts of graffiti sometimes
Steel wool can work if you scrub long enough
Oven cleaner sometimes helps

What motivates people to write on the inside of a bathroom stall?

My smart-alecky answer is:

  • There is not much else to do.  Restroom owners are very inconsiderate in not providing the appropriate level of entertainment.
  • The best inspiration in life comes from when you're sitting on the can taking a dump.
  • It's the only place aspiring amateur artists and writers will find a captive audience.

But the more mature and responsible part of me is forced to write:

They are oblivious to the fact that…

  • …few people are enjoying their scribblings/artwork nearly much as they are.
  • …they are creating an unwanted eye sore for others.
  • …their vandalism is wreaking havoc on someone else's business, via increased maintenance costs and, possibly, resulting higher prices

Graffiti: What is the most intriguing piece of writing you have seen on the inside of a bathroom stall?

Though I never had the opportunity to view it, there are three urinals in Van Pelt Library at the University of Pennsylvania bearing plaques with the following inscription:  The relief you are now experiencing is made possible by a gift from Michael Zinman.

What is the geekiest graffiti in the Bay Area?

I just like that there's an artist that goes by DotCom: http://www.fatcap.com/artist/dot…

A lot of the municipalities, most notably SF, have cracked down significantly in the past 5-8 years on graffiti, which is really sad for our community (IMO).  Most artists risk too large of fines or punishment by putting up work where you would actually be able to see it.

Who are the best or most notable street artists in the world?

First, "best" is in the eye of beholder, "most notable" defined by the number of people from the general population that could recognize their name or work might be more accurate term.

We're keeping Street Artists separate from Graffiti Artists, which is a good call.  Os Gemeos, ROA and BONOM all ride the cusp between the two.  All graffiti artists are street artists, but all street artists are not graffiti artists.  Pure street artists do wheatpastes and stencils primarily, but branch out into stickers, signs, characters and figurines as well. 

Here are some artist pages for the most "notable" street artists.

Where's the best street art and graffiti in the Bay Area?

The Mission is by far the best destination for San Francisco graffiti, but the movement in the Bay Area has shifted significantly to the East Bay, primarily in Oakland.  In the Mission, Clarion Alley is a great destination with a featured piece by Chor Boogie (http://www.fatcap.com/artist/cho…).  He also has work on Market Street. 

I suggest walking east on 24th street from Mission towards Potrero, and you should catch one of Swoon's pieces on a side street, and some markets that have allowed graffiti artists to come by and paint. 

Finally, off 22nd between Valencia and Mission, you'll find some murals, but they've been bombed pretty hard by some taggers recently.

Funkandjazz aka Steve Rotman is one of the most prominent photographers in the Bay Area (see: http://www.fatcap.com/article/ba…) and following his Flickr account is a must if this is something you are interested in.
