Fresh after the festivities of the 20th anniversary of the Berlin wall falling, another event lands at the East Side Gallery in the spirit of freedom. Justin Tellian’s The Dreamers project, which started in Brooklyn, has embarked on an intercontinental world tour with stops along Mexico City, Berlin, Tokyo and finally Johannesburg with one message: wear white, and dare to dream big.

This Saturday, Tllian invites everyone—”artists, poets, musicians, schoolchildren, lovers, and creators of all kinds”—to join him as he takes portraits along the symbolic 1.3-kilometer stretch of the wall of those people courageous enough to call themselves dreamers. But of course: an after party, location TBD, will follow.
