If you're in London, and feeling slightly let down in the gap between Olympics and Paralympics, don't forget that Brazil's Olympic House is still open. Since Rio is hosting the games in 2016, there are previews of the city, the stadium and the Olympics and Paralympics logos - but also exhibitions highlighting contemporary Brazilian art and design.
It's all free, conveniently located in Somerset House and, as IanVisits has pointed out, has a shop which is already selling souvenirs for the forthcoming games. Altogether, enough Olympic spirit to tide you over until the Paralympics start at the end of the month!
Casa Brasil is open 8am - 7pm daily until 9 September; admission free.
