*sigh*
Pretty!
I once worked for a mad inventor, whose primary project was problematic in that it was a biomass convertor in which he proposed to use every carbon atom twice as output. However, he did contrive an amazing manufactured greenhouse roof beam out of cedar. He ripped the cedar down to 12' long half-inch thick by two inch wide strips, and then made a double-compound curve by nailing and gluing the strips on shaped blocks: the lean-to greenhouse I made with those beams survived the Thanksgiving 1983 storm on the windward side of the house. I thought later when I was splitting my own boards that cedar split on-grain rather than sawn would be even stronger.
His proposal for the top header of a free-standing greenhouse involved a similar compound beam with the top block of the verticals meeting at another block, and the whole thing being an integral glue-lam joint.
Explaining this works better with a chalkboard, by the way. Also possibly with much more coffee.
