what is a HILAL (we designed one and got it made)
Hilal (Arabic: ????, hil?l), a crescent. the crescent Moon visible after a new Moon, determining the beginning of a month in the Islamic calendar.
I was trawling through some of our archive material and realised I’d nearly forgotten the experience we had designing a Hilal to adorn the small Islamic prayer building we worked on a few years ago. It caps the roof in the manner of a finial adornment. With some encouragement from our client we worked out this crescent moon shape as a geometry generated from intersecting spheres. It was produced by a local maker who adopted modern machining principles to create from solid aluminium.
