An image of a smiley face was projected onto the Houses of Parliament to spread an uplifting message of positivity during tough times.

Any smile-but especially one that is 27 yards wide-can go a long way to cheering people up, especially when it's directly across the river from a hospital.

The lipstick-wearing smiley was beamed onto the famous structure last night, on the eve of World Emoji Day.

The positive image was in full view of St. Thomas's hospital, and it stood as a reminder of how good it feels to smile. Passersby who saw the images last night said it brightened up their evening considerably.

"Seeing the smiley made me laugh," said Dave Crawford. It's also opposite a hospital, and you hope that people get to look out and see it."

Everybody knows we need more smiles right now-especially because it's hard to know if people are smiling behind their face masks.

Another onlooker, Kate Sandison, said the projection was a great surprise. "It looks great and makes you feel good. It made me smile."

Commissioned by the cosmetics company Ciaté London, founder and CEO Charlotte Knight said they designed a new range of Smileys that include lashes and lipstick, created in partnership with the originators of the concept.

"Particularly at times like this it's important to see the positives in everyday moments by sharing smiles."
