TurtleStitch

TurtleStitch is a visual, blocks-based programming environment for turtle graphics with a primary focus on embroidery.

Generated graphics can be exported as a embroidery file (currently Melco/EXP and Tajima/DST are supported) and SVG images.

TurtleStitch is based on Snap! Build Your Own Blocks written by Jens Mönig and Brian Harvey.

It uses webgl ThreeJS as rendering engine for performance as smooth as possible.
