Dynamic ART

Introduction

Dynamic ART is a graphical programming environment on iPad. It's easy to create amazing artwork, animations, interactions and music with Dynamic ART. You can also share your creations with your friends.
You don't need to study complex syntax of computer languages. You just drag and drop a set of blocks and connect them together. It will be a fun way to build your own programs.
It can be used for beginners to learn and practice mathematical, computational ideas and creative thinking.

If you have any questions or suggestions, please sent e-mails to codingpotato@gmail.com.

Features

Multi-programs management.
Graphical programming by dragging and dropping.
Program executing flow control and sub-block-sequence reuse.

Spinning

What will happen if six turtles at the corners of a hexagon each moving towards the one to its left? This example will show you the result!

Attractive Point: Amazing spire with gradient color.

Note: This example is used for the Dynamic Art for iOS icon.
