Planning to visit London on a budget could initially give a Cheapo a nervous breakdown. But, as documented throughout our London guide, it is possible to live it up in London on a modest budget — with a little planning.

How? Besides the obvious (choosing a budget hotel, eating cheaply, and getting around with an Oyster card), you’d be crazy not to take advantage of London’s free museums and attractions. Most of the nationally-run museums and art galleries are publicly financed and don’t cost visitors a pence. It’s a beautiful thing…

Ok, so a recent installation at the Tate Modern in London kinda cracked us up.

The exhibit, by Colombian artist Doris Salcedo, is called Shibboleth and is a 167-meter long crack in the floor. Museum goers are invited to interact with the exhibit. A story in the AFP says, “some visitors have been so distracted by the impressive surroundings that they have unwittingly fallen into the crack, around one foot (or 30 centimetres) wide in places.” The crack gets filled next April.

For more on the artist, check out the Tate’s site.

Across town at the National Portrait Gallery, a huge pop art exhibit opened today. The usual suspects—Andy Warhol, Roy Lichtenstein and David Hockney—are among the 52 artists represented. The exhibition runs through January 20th, 2008. More info at the Gallery’s Web site. Price: £10.

And, if you’re in London—whatever you do—please, for the love of art, go to the annual Frieze Art Fest. It’s on until October 14th and, though it will set you back £18.50, you’ll feast on the works of more than 1,000 artists the world ’round.
