Cake Inspiration: Geometry inspired Cakes

I've been trying to move beyond floral inspired cakes, just for a change of design since most of my cakes thus far have been mostly floral designed. Geometric inspired cake designs are a very popular and interesting options. They really transform the look of a cake, making them seem more modern and just have a different vibe from traditional fondant cake designs. They has a edginess to them that's so fun and fresh, something I'd like to recreate this summer. All nine of the cakes are ones I'd love to recreate, each of their own unique spin on geometric patterns, some more classic like #s: 5-9, while others have a wild streak like #4 (that's such a fun cake..)

Hope everyone is enjoying the warmer months! As always, comments, questions, and suggestions are welcome.
