Code Snippet

import e32
import random
import time
import appuifw
import graphics
import math
 
appuifw.app.title = u"Random Rectangle-2" #set the application title
can=appuifw.Canvas() #create a canvas class
appuifw.app.body=can  #assign the canvas to the body
img=graphics.Image.new(can.size) #create a new image instance
img.clear(0xffffff)     #clear the image
 
running=1
 
def quit():
    global running
    running=0
 
appuifw.app.exit_key_handler=quit
 
while running: # below acript makes the random rectangles
 
	for i in range(1,70):
	    a=random.randrange(255) #defines the position of the rectangles
	    b=random.randrange(255)
	    c=random.randrange(255)
	    j=i+1
	    x1=(can.size[0]/2)-j #defines the position of the rectangle
	    y1=(can.size[1]/2)-j
	    x2=(can.size[0]/2)+j
	    y2=(can.size[1]/2)+j
	    img.rectangle((x1,y1,x2,y2),outline=None,fill=(a,b,c))
	    img.rectangle((x1+10,y1+10,x2-10,y2-10),outline=None,fill=0xffffff)
 
	    can.blit(img)
	    e32.ao_sleep(.1)    
	e32.ao_yield()
