# Sierpinski 10Liner (ZX81)

# Sierpinski Triangle 10 Liner

Sierpinski10Liner is a simple Sinclair ZX81 BASIC language implementation of the Sierpiński triangle fractal construction using the chaos game algorithm.

The program is made up of 10 (actually 9, the last is just a REMark statement) BASIC lines with one statement per line and is the improved version of a similar program I made some years ago. It should run on any un-expanded (1KB RAM) or expanded ZX81 computer or clone.

Sierpinski10Liner is my entry to the BASIC 10-Liner Contest 2020, SCHAU category.
