Geometry crochet

Of late, there has been an increase in interesting forms of crochet...and one of them is Sea Geometry
This website shows amazing freeforms, geometrical crochet, to form a wonderful arrangement that ends up looking like something you would find in the sea or aquarium. Beautiful sea forms off all shapes and colours created by a single hook and yarn of all colours and thickness. If you have the change to look at the site, you will be surprised at the beauty that has been created. I know I was.
If you know how to make one or all of those sea creature items, please feel free to share your patterns, blog or ideas.
