I popped down to Potters Field Park this afternoon for the launch of Portavilion – a portable tent that’s coming to an open space in London near you this summer.

Rosy (the ballerina) is the semi-opaque tent’s name. Appropriately, the opening event inside Rosy was a Big Dance performance by the Siobhan Davies Dance Group in association with Sadler’s Wells. (Read about the launch of Big Dance this morning.)

Although the show was aimed at kids aged 3-7, I really enjoyed the 10-minute performance, which incorporated rubber balls, a cello and lots of bouncing and sliding.

To see Rosy for yourself this summer, check out her locations and performance times (you can visit and enter even if nothing’s on) at www.portavilion.com
