1,2,10|13,2|34,13|-8

The app generates images based on a set of input parameters which are displayed at the bottom of the screen. Use Left/Right to move between the input boxes and Up/Down to increment/decrement.

Inputs:

1. The number of points to start with. 3 = Triangle, 5 = Pentagon/Pentagram
2. The distance between points that are connected with a line. Usually 1 is good but for a Pentagram you would use 2. You can try other values
3. and after: The number of times to repeat the previous item.

Controls

• Left/Right: Navigate between the boxes
• Up/Down: Increment/Decrement. Setting the last segment to 0 will remove it. Increment the empty segment will add a new one
• J/K/L: Animate Forward/Backward. K will stop the animation. Only works on the repeats, not on the first two

Todo

• Add coloring
• Add rotation
• Add timing controls
• Add export
• Add onion skinning
