@scruss The PICTURE command can group objects, and also output SVG animations. Although I’ve made a screen recording here as animated SVGs aren’t accepted

@scruss Nice, this version has a few changes to fill the shapes with PENDOWN and PENUP to avoid draw extraneous lines.

@scruss Thanks. Here’s the Sierpinski program adapted to run LibreOffice using the built-in LibreLogo environment https://help.libreoffice.org/latest/en-US/text/swriter/librelogo/LibreLogo.html

One of LibreLogo’s advantages is that the output is vector graphics that can be edited (but rasterised here for convenience).
