The Triangle Notebook is a quirky take on the traditional journal. Although still a simple, geometric shape, it really re-imagines one's relationship not only with notebooks in general. The interaction between user and diary is slightly tweaked, enough to make you analyze every word jotted down and every space filled.
Designed by Tan Mavitan, the Triangle Notebook is also nifty because it uses less paper material, which is obviously good for the environment. On a more practical level, its smaller size makes it easier and more convenient to carry around. Considering that many people can use their phone to take notes now, this Triangle Notebook redesign makes you want to use a physical journal again.
