Choose "all nums" or only "primes." Adjust "color" and "scale." Compare "all numbers" with "prime" patterns. Color highlights secondary patterns, especially in "all nums" (by using the mod function). Spacebar to see list of primes. "H" hides list.
Numbers plotted with polar coordinates. If choose "all numbers" then it plots 1, 2, 3, 4, etc. If "primes" it plots only 3, 5, 7, 11, 13, 17 etc. For example, for the number 3, the pen faces the direction 3 and moves 3. Direction in radians. "All numbers" plots as smooth spirals. Primes plot as spirals with gaps. This may bust some myths about prime plotted with polar coordinates. The spirals results from using radians (sets pi, a very irrational number at 180 degrees). See my project on "phi vs pi from several years ago using degrees not radians. Prime numbers actually have less spiraling but some mathematicians thought the primes, because they are associated with chaos, would have no spirals at all. Scale alters the size of the move. Prime numbers exported and imported from my prime number project, using lists. Smaller dots help see the pattern for some scales.
