Only Ten to hundred lines of code to make a very small paint game for kids In a smart way

i think the idea is cool

just one loop will create small objects (circles or rectangles) to fill the screen
each object will have the same touch event which will fill the object with a randomly selected color

add a few lines to have different background color, and different sizes for your objects

so as you touch your screen you are drawing rainbow colors

very fun specially when your phone has a stylus
