There are 10 pens, hitting 0 - 9 will activate one pen which you can give its own individual seed. Enter a seed to tell the project what to draw Putting "r" instead of a seed will generate a random seed The first 6 digits are the starting coords the 7th and 8th digits are the starting color the 9th and 10th digits are how many degrees the pen will turn the 11th and 12th digits are how many steps the pen will take the 13th digit is how much the color will change xpos color move | | | [000][000][00][00][00][0] | | | ypos turn color Negatives are still valid -13-1218-2-90 is a valid seed 0000000000000 is NOT a valid seed as it is equal to 0, and the program divides the seed by 1 to test that the seed consists only of numbers, and if the seed is equal to zero that means it couldn't divide by 1 and it returned nothing, meaning either the seed is equal to zero or has disallowed characters in it.
Thank extreme boredom for this project if for some reason you enjoyed it ¯\_(ツ)_/¯
