Launched in 2014 Geometry Club is a simple premise, with stunning results. There are two rules:

1) Your apex needs to be aligned centrally on both the X and Y axis
2) Edges should fall off the image at the same point, symmetrically

With over 50 approved contributors in 20 countries anyone can submit a photo to be featured, but it seems only those meeting the exacting criteria will be featured. The outcome is a mesmerisingly beautiful geometric feed of architectural precision.
