Traditional Buildings

[Mostafa]

I'm currently involved in the design of a traditional building (reflects local heritage and tradition). The building comprises a number of rooms ,of various sizes, that encompass an open court. As the building is centrally air-conditioned, the client wants the open court be covered with a multi-media screen (size: 25x25m) that can be used for displaying weather emulations (summer: clear skies/clouds, winter: dark clouds/thunders/heavy rains). I've tried to locate a supplier who can cater for this job
Or, someone who can suggest a supplier / an alternative but with no luck. Can anyone offer a solution for this problem?
Looking forward to your contributions in this matter.
Thanks, Mostafa
