ICYSCs provides 21st century integrated hub in every district in Hong Kong for kids from age 6-24 to learn STEM, wellness, sustainability and innovation, career and life development. We designed a mascot, "Si Jai 匙仔", who is the shape of a keyhole. It represents the action in moving onto the unknown challenges and new knowledge. Si Jai has The Thinker Eyes, a pair of confusing eyes illustrating the think process, processing different possibilities and answers. There are a family of Si Jai with different height and shapes symbolising every different one of us.
