PVC pipe exotic joint BETA

A threeway 60 degree pipe joint for 1/2 inch schedule 40 pvc pipe. 4 of these should make an Isosceles pyramid, or a PVC TeePee. I'm really hoping somebody takes this idea and makes it better. And other variants could produce scaffolding, or a really big tinkertoys set. Break out of the 90 and 45 degree rut the Hardware store imposes on you.
