The Pythagoras Tree is math art. A square trunk is drawn. The hypotenuse of a right triangle is laid on top of the square. From the two legs two new squares are drawn. This process is repeated recursively until there the size of the square is too small to draw. Here you can adjust the angles of the triangle and the color of the tree. You can also make the tree grow and shrink to see the steps in making the tree.

About

Happy Patterns

Features
Read full description

Happy Patterns is a collection of interactive visual art for iPhone, shaped through colour, motion, mathematics and careful craft. It is made to bring small moments of curiosity and delight. There is no feed to follow, score to chase or task to finish. Instead of asking you to keep scrolling, Happy Patterns gives you visual pieces worth spending time with. THREE VISUAL WORLDS ATTRACTORS The mathematics of chaos transformed into flowing three-dimensional forms. MANDALAS Symmetry, colour and repeating motion unfolding from the centre. BLOOM Layers of petals, movement and carefully chosen palettes coming together as ever-changing flowers. TOUCH, TILT AND EXPLORE Every pattern has its own character, controls and small surprises. Turn a form with your finger. Tilt your phone to change the perspective. Adjust the movement or colour, or randomise the parameters to explore a new variation. When you want a quieter view, hide the interface and let the pattern fill the screen. CAPTURE AND SHARE Save the moments you like as images or videos, then share them with other people. MORE TO EXPLORE Each world is ready to explore from the moment you open the app. Optional one-time purchases unlock more patterns within a world or the fixed Launch Collection of Attractors, Mandalas and Bloom. Happy Patterns will continue to grow with new visual worlds, each developed with the same attention to beauty, interaction and detail.

Happy Patterns's advantage is update cadence (fortnightly vs every 21 months). On price and ads there is nothing between them.
