Found an interesting Tiling Pattern Maker written in JavaScript that makes and saves patterns to SVG
https://github.com/aatishb/patterncolliderRuns in Firefox browser.
Uses grids of lines to explore symmetries.
Has many options to: Change patterns, Colours, Sizes.
Use the sliders at the bottom of the loaded JavaScript page to make your patterns.
Might be REALLY NICE to convert to Lazarus?Attached are some samples
(I saved to png and compressed them for the forum to reduce file size. The originals are much more colourful)
