Recently, movable electronic laughing mirrors were co-developed by the IT Institute of Kim Chaek University of Technology and the Information Exchange Company under the Rungna People's Pleasure Park Management Office and debuted at the pleasure park.

The mirrors show scores of varied images, causing great laughter among visitors.

Yang Ho Rim, president of the company, told KCNA that researchers developed software and designed wry shapes to get greater laughing effects.

It is expected that such mirrors would be sent to pleasure parks in different parts of the country.
