Keith,
Weeping plaster was extensively used at the Aga Khan University Hospital project in Karachi, Pakistan. You should be able to find lots of pictures of this project in the digital library of ArchNet. I worked on the project during its construction phase. Its application was quite labor intensive using a very basic and simple technique of squeezing a certain amount of plaster out of a plastic container, fitted with a nozzle, and letting the plaster roll down the surface. The overall finished effect turned out to be quite impressive. I do not have any information on its cooling effect. You may contact Payette Associates in Boston. They were the design architects. I hope this helps.

Strange. Flat surfaces are easier to clean and keep free from germs. Because from the description, allowing plaster to flow downwards on walls would have the uneven surface appearance of limestone caves. (?)

In reference to John's comments, this is primarily used for exterior walls as facade treatment.
