If you have $5

Go on a search for free public art – in a portable toilet. A project called Found Sound has placed five portable toilets in various locations around the city, where they serve as listening booths for the work of curator Welmoed Laanstra until this Saturday. You have to go inside the venue that is “hosting” the potties for a key. And no, they don’t function like portable toilets do – thank goodness. For locations, go to www.welmoedlaanstra.com.

If you have $10

Learn to shake and shimmy your hips like Shakira at Meze, which offers free belly-dancing lessons every Sunday evening at 10. Come early for some delicious Turkish food – the tapas are rumored to be excellent – and then stay for the lessons by belly-dance expert Noor-Jihan. Meze is in Adams Morgan, at 2437 18th St. N.W.

If you have $20
