Stuyvesant High School freshman Christine Kim was in 1st grade the last time students from her school applied brush to the wall outside Washington Market Park’s tennis and basketball courts on Chambers Street. Now, eight years later, she was adding her own fresh, fanciful imagery to the fading mural called “Alice on the Wall.”

Her painting includes Alice (in Wonder­land) and an unidentified male gazing toward a distant castle. It is joined by other dreamlike scenes by other students such as giant mushrooms, Pac Man in headphones, a book turning into birds and a sheep-making machine.

As the school year wound down last month, Kim and other Stuyvesant students—as well as passersby—were at the wall each day, restoring some of the old paintings, but mostly creating their own.

“I think of all the people who are go­ing to pass by and look at it,” Kim said. That huge, accidental audience for the work of young New Yorkers—along with community involvement—is the goal of CITYarts, the non-profit org­an­ization that sponsored both the original mural and the newest version among many other public art projects in New York.

“The idea is to respect the past but to go with the future so it will be a little bit of restoration and a little bit of new thoughts,” said Tsipi Ben-Haim, the executive director. “It’s a new generation.”

Many of the artists were part of the crowd that hung out at the wall after school, and it was there, under the direction of  creative coordinator Jordan Taler, that they sketched their ideas.

“The people who stay at the wall tend to be the people I know so it’s always meant a lot to me,” said senior Adam McCombe, who was putting the finishing touches on his version of the Mad Hatter.

“I kind of wanted to leave a mark on the school,” he added, “so I thought, this is my last chance.”
