On March 4, 2022, the opening ceremony of the Winter Paralympics was held at the Bird's Nest in Beijing.

A group of impaired individuals came together to create a piece dedicated to the Winter Paralympics. They choose their favourite colours and place them in balloons with detonators. Then wear a brainwave-capturing device that sends a signal to trigger a detonator to detonate a balloon, and paint is sprayed on the canvas. The colourful intersections form an abstract “smiley face”, which means welcoming friends from all over the world with laughter.

Disable people are not defined by their health conditions or impairments. Combined with the technology of brain wave idea control, the mental power expression of the disabled can be visualised.
