To Do's

• find appropriate LICENSE
• create a fun homepage
• parse the numerical input and use it as a variable for the spiral color, length, ... (angle should be at least 35)
• create a "best of" of the parameters: angle 225 is really cool! With angles after 90° the spiral twists! Try 3456
• adding a slider for changing the color of the background: B/W or RGB?
• add the possibility to press the key "enter" for starting a new spiral
• possibility to save the canvas as an image, pdf or GIF
• possibility to send the image via email
• make the homepage responsive
