1st prize in an art competition organized by the Ministry for Building and Housing of the Land of North Rhine-Westphalia.
The task was to develop an overall artistic concept for two prison chapels (for men and women): colour and illumination concept, altar, ambo, altarpiece and floor design.

"Gläsker created for Gelsenkirchen two meditation rooms that are open to all faiths... These rooms take the inmates out of their daily prison grind. They offer – to use the artist's own words – "space for deep-breathing and reflection"... Here the inmates are afforded, through their confrontation with art, the opportunity to enter into an unusual, elevating dimension of being. The rooms stimulate and mobilize thinking and feeling for those areas of experience that have a meaning of sense and order for human life and co-existence. Thus they can give important impetus for spiritual meditation, for change, for resocialization... the meditation rooms neither convey nor figuratively depict any specific religious content but rather open themselves, through their pure abstraction, to cosmic themes, to the idea of a universal creation that unites all faith communities. The forces of the universe, which every human being senses within himself and perceives in the natural world around him, become vividly clear."
