In this example three corners are formed in a single column by bending the balloon filled Rouse Matrix. The two columns are made from an RMS Builder. The arch itself is a Standard RMS "Queen's Arch". The Queen's Arch maintains the tiangular cross section of the columns while it forms the curve automatically.

This photo illustrates a cross between the smooth curve of a cone and the sharp bend of corners. This is an RMS "Umbrella", another Standard RMS product. Like the Queen's Arch, it is self forming when loaded with balloons. When reproduced on a larger scale these "puffed pentagons" can make large canopies and even geodesic balls.
