Before I broke my computer, I had posted 2 versions of Sierpinsky decorated.bas and .sdlbas. I was intending to post at bp.org but waited too long.
If you have an Android device, you can download SmallBASIC for free at Google Play and run first on-line sample (and all the samples of course) to see code in action.
To see code... goto SmallBASIC.sourceforge.net Code Library Graphics2, Sierpinski Decorated.bas or sdlbasic.t15.org, same title Under Projects Board.
Thanks to PeterMaria for code snippets that inspired idea and Johnno56 for his input for coloring.
