You can once again visit the crown of Lady Liberty. Ticket sales online resumed this morning after a multi-year pause. Visits begin July 4, but the first few days have already sold out. The cost for adult admission is $15, including the cost of the $12 ferry ride and access to the rest of the national park. Although the base, pedestal, and lower observation deck reopened to the public in the fall of 2004, the crown has remained closed since 9/11. But an interior redesign has now made it possible to evacuate people from the top in case of an emergency, and the Statue's crown once again offers views of the harbor. Park officials are responding to a big downturn in visitor numbers: 3.6 million people visited the Statue of Liberty in 2000, but six years later, that number had gone down to 2.5 million. —JD Rinne and Sean O'Neill

If art museums and stodgy art galleries aren't really your thing, be sure to check out Figment on Governors Island in New York City this weekend. The celebration, now in its third year, was created as an alternative to the city's traditional art scene—the completely free outdoor event encourages collaborative and participatory projects. Attendees essentially become artists for a day. The festival's name comes from Andy Warhol, when he was asked about his tombstone: ''No epitaph, and no name. Well, actually, I'd like it to say 'figment.' " There are a ton of events and projects scheduled, starting on Friday. They range from something as simple as a coloring table or a community poem to the elaborate-sounding Chorus in a Box, where participants dial their cell phones to get a looped tape of a song, which they are then encouraged to sing (or something…sounds like you have to be there). Some other interesting activities include Hula-hoop dancing, a Plant Parenthood adoption event, and a Frisbee-designing session, sponsored by the Children's Museum of Manhattan. There's also an artist-designed mini-golf course and a sculpture garden. The 2008 celebration attracted more than 10,000 participants, and organizers say they're expecting more this year. The only thing they ask you to bring? Your creativity (and maybe a snack). Another happening of note in New York City this weekend is the World Science Festival with speeches by prize-winning scientists and other programs. Figment is Friday through Sunday and free. There's a free ferry to Governors Island. For more info, go to figmentnyc.org.

Luminato, a festival of arts and creativity, will host more than 140 music, theater, dance, arts, literature, and food events in Toronto, all in the hopes that regular people will have an "accidental encounter with art." Most of the festival's events are free—public art installations, dance parties, short film presentations (including a quadruple feature of animated Edgar Allan Poe stories), and street performances make up the bulk of the scheduled activities. The festival starts Friday and goes for 10 days. The schedule is massive (try this at-a-glance calendar to make sense of it all), but it's easy to spot a few highlights: On Saturday, the festival organizers will attempt to break the Guinness World Record for the largest guitar ensemble. The current record is 1,802 guitarists performing together—Luminato has invited 2,000. In a public vote on the event's website, Neil Young's Helpless won as the chosen song for the attempt (download the music and lyrics here). Luminato also brings some cool public art installations to Toronto. One highlight is Binary Waves (pictured), in Toronto's financial district. The work lights up when there are invisible electromagnetic communications signals present—you can imagine what it looks like at 5 p.m. on weekdays. The installation is part of a work called Communications/Environment. Next weekend, sample the city's cuisine for just $5 an item in the 1,000 Tastes of Toronto event. If you're looking to make a vacation of it, note that more than 30 hotels are offering hotel packages, with some including event tickets. Find out about admission to ticketed events here.
