When this installation was first unveiled in the CBD area, it read ‘SFMRIOLWEN’. The letters forming the word FROWN were made of ice and melted away in a few hours, leaving us with the word ‘SMILE’. The message? Problems will come and go. The 3m-high sculpture, the second in Health Promotional Board’s Positive Art Series, is now on display in East Coast Park between McDonald’s and Long Beach restaurant.
