Glad to see Forth on HN today! For anyone who likes playing with small experimental projects, I once made a minimal, esoteric canvas colouring language inspired by Forth and Tixy: https://susam.net/fxyt.html https://susam.net/fxyt.html

Very cool! It would be even better if you had a Library of preset demo programs for people to hack and see the power of your tool Edit: I saw them on GitHub. But I've also seen some tools that put them in the main interface. That would be an improvement IMHO. Great work!

  Thank you! Glad you liked it! There are a few demos at the bottom of the help screen, which can be invoked by typing '?'. You are right that that they could be better linked directly from the main interface. In any case, here are the direct links to the demos available in the help screen: https://susam.net/fxyt.html#XYxTN1srN255pTN1sqD https://susam.net/fxyt.html#XYxTN1srN255pTN1sqD https://susam.net/fxyt.html#XYaTN1srN255pTN1sqN0 https://susam.net/fxyt.html#XYaTN1srN255pTN1sqN0 https://susam.net/fxyt.html#XYoTN1srN255pTN1sqDN0S https://susam.net/fxyt.html#XYoTN1srN255pTN1sqDN0S https://susam.net/fxyt.html#XYpTN1srN255pTN1sqD https://susam.net/fxyt.html#XYpTN1srN255pTN1sqD https://susam.net/fxyt.html#XYN256sTdrD https://susam.net/fxyt.html#XYN256sTdrD Community demos are available here: https://susam.github.io/fxyt/demo.html https://susam.github.io/fxyt/demo.html

This is fun! I was going to try to draw a circle but was missing sin/sqrt. Then I thought of using a lookup table but got stumped. Do you have any pointers for drawing a circle? I'm looking at demo #4 (https://susam.net/fxyt.html#XYpTN1srN255pTN1sqD https://susam.net/fxyt.html#XYpTN1srN255pTN1sqD) to see where the circular shapes are coming from. Have you seen Forth Haiku? https://forthsalon.appspot.com/ https://forthsalon.appspot.com/

  doesn't need to be accurate, could do something like this (distance + treshold) : https://susam.net/fxyt.html#XN128dXN128dpYN128dYN128dpsN4096lN255pC https://susam.net/fxyt.html#XN128dXN128dpYN128dYN128dpsN4096... smaller with dup : https://susam.net/fxyt.html#XN128dDpYN128dDpsN4096lN255pC https://susam.net/fxyt.html#XN128dDpYN128dDpsN4096lN255pC circles pattern : https://susam.net/fxyt.html#XDpYDpsN8qN3riN255pC https://susam.net/fxyt.html#XDpYDpsN8qN3riN255pC PS: fun tool !

    Oh, thanks! X^2 + y^2 > z^2 ? 1 : 0

  Was also gonna jump in with the old way of doing circle boundaries, which can be done all integer: https://en.m.wikipedia.org/wiki/Midpoint_circle_algorithm https://en.m.wikipedia.org/wiki/Midpoint_circle_algorithm
