I think most people who live in the Southampton area will have seen something in the media/social media about the street art of Southampton artist Will Rosie.
His mosaic Squojis (square-emojis) started to appear around the town during lockdown. They started out as mysterious, anonymous street art, with the invitation to search them out and post on social media. They were quirky little fun items but IMO a brilliant piece of advertising of his art: https://squoji.co.uk/about/
