The WXYZ, created by Tung Ken Lam, had set in motion the creation a series of planar models by various origamists including Francis Ow, David Petty, Satoshi Kamiya and Meenakshi Mukerji. The WXYZ is among the simplest of the planar models and is made up of 4 intersecting triangles.
It is quite simple to fold though the assembly will take up some time. I am glad I finally managed to do a planar model though the colour combination isn't the greatest! The red and orange together don't stand out quite that well.
These models have a unique naming convention, which is based on geometric principles. The number of letters used is the same as the number of planes in the model. Thus WXYZ would mean it has 4 planes.
