Here's a quirky application which was developed to help travellers get round the language barrier.
Image It 1.1 aims to help globetrotters make themselves understood in any situation by using pictograms to communicate what they need.
The application does not require an internet connection and lets users pick from more than 450 pictograms to put a sequence of up to three together to convey a message.
Users could, for example, put together images of a taxi, the airport and a currency symbol.
Image It, which works on iOS and Android devices, already has a number of set categories such as food, emergencies, accommodation and transport.
The app also enables users to create their own pictograms, insert pictures from their phones and draw or write on existing pictograms.
The idea originated from a traveller who injured himself on a trip to Laos and needed to ask locals where to get hold of bandages etc.
