KaleidoCurve app for iPhone and iPad

Doodle up complicated patterns from simple curves that you can go back and edit, or save as copies. Create new sequences of color gradients that apply to each rotated version of the curve. Drag out a smooth bezier curve with the pen tool and you can edit as you go. Explore how simple shapes create complicated patterns. Curves and gradient color sequences can be saved as named files and reopened for editing. Become familiar with Bezier parametric cubic curve drawing as used in popular vector drawing programs and try out the options to edit point types and handles.
