Each year at the Annual Livingetc Summer Picnic, Neil, our deputy editor, devises a fiendishly tough quiz to test our knowledge of all things interiors and design (and plenty of random other stuff too).

For a team of hip clued-up design professionals we are always embarrassingly clueless.

But hopefully next year this iPhone app from Fail Forwards will spare our blushes. Design Icon: Chairs is a quiz which asks the player to identify classic chairs from the last century from their silhouettes. So if you know your Wegner from Jacobsen – or have a need to know the difference – this is the app for you. Damien Breen, senior designer
