On 2nd November at Christie’s in London, five new artworks by Prince Nikolaos of Greece were unveiled. They are known as Soundwalls and feature a huge video display powered by a Raspberry Pi. The Pi also provides a soundtrack to the exhibit using a pre-selected playlist. The unveiling was attended by Prince Michael of Kent and King Constantine of Greece as well as many other luminaries from the arts field.
