Covent Garden floating artwork wows crowds
British Artist Alex Chinneck has created an artwork at the market place in Covent Garden that makes the facade of the Piazza look like it is floating.
The effect which can be seen from any angle makes the building appear to break away from the columns. Over 100 people worked on the project which will be in place until the end of October.
Chinneck has called the work 'Take my lightning, but don't steal my thunder'.
Alex spoke to BBC News about the project and how he achieved the final result.
