Years ago I wrote a little screen-saver in Delphi that randomly put colorful circles all over the screen. A hit with the secretaries in the office. I modified a simple Tkinter based snippet to put the same colorful circles all over a window form at random locations, random radii and random colors.
Random Graphics (Python)
# random circles in Tkinter
# a left mouse click will idle action for 5 seconds
# tested with Python24 vegaseat 14sep2005
from Tkinter import *
import random
import time
def idle5(dummy):
"""freeze the action for 5 seconds"""
root.title("Idle for 5 seconds")
time.sleep(5)
root.title("Happy Circles ...")
# create the window form
root = Tk()
# window title text
root.title("Happy Circles ...")
# set width and height
w = 640
h = 480
# create the canvas for drawing
cv = Canvas(width=w, height=h, bg='black')
cv.pack()
# list of colors to pick from
colorList = ["blue", "red", "green", "white", "yellow", "magenta", "orange"]
# endless loop to draw the random circles
while 1:
# random center (x,y) and radius r
x = random.randint(0, w)
y = random.randint(0, h)
r = random.randint(5, 50)
# pick the color
color = random.choice(colorList)
# now draw the circle
cv.create_oval(x, y, x+r, y+r, fill=color)
# update the window
root.update()
# bind left mouse click, idle for 5 seconds
cv.bind('<Button-1>', idle5)
# start the program's event loop
root.mainloop()
