happy (tkinter) easter 2007 folks!

[kudos]

Hi, a couple of months ago, I made a xmas chistmas "card" to this community(http://www.thescripts.com/forum/thread580722.html) Now its soon easter, and I hacked together something for easter as well....

import Tkinter
import random
import colorsys
import time
 
# Happy easter 2007 folks! from [e-mail]
 
playerx=170
bar = 0
ball = 0
ballvx = ballvy = 0.1
ballx = 200;
bally = 150;
 
def motion(event):
 global playerx
 playerx = event.x
 if(playerx < 400-60):
  w.coords(bar,playerx,250,playerx+60,250)
root = Tkinter.Tk()
w = Tkinter.Canvas(root, width=400, height=300, background="#000000")
w.bind("<Motion>", motion)
ball = w.create_oval(ballx-3,bally-3,ballx+3,bally+3,fill="#cccccc") # ball
blocks = []
k = 0.0
for j in range(10):
 for i in range(10):
  c =  colorsys.hsv_to_rgb(k,0.5,0.4)
  d = hex(int(c[0]*256)<<16 | int(c[1]*256)<<8 | int(c[2]*256));
  d = "#"+d[2:len(d)]
  k+=0.01
  blocks.append(w.create_rectangle(40*i,(j*10)+10,40+(40*i),20+(j*10),fill=d))
bar = w.create_line(playerx,250,playerx+60,250,fill="#ffffff")
w.pack()
try:
 while 1:
  w.coords(ball,ballx-3,bally-3,ballx+3,bally+3)
  if(ballx+ballvx > 400 or ballx+ballvx < 0):
   ballvx*=(-1)
  if(bally+ballvy < 0):
   ballvy*=(-1)
  for block in blocks:
    crash = 0
    co = w.coords(block)
    if(ballx+ballvx > co[0] and ballx+ballvx < co[2] and bally > co[1] and bally < co[3]):
     crash=1
     ballvx*=(-1)
    if(ballx > co[0] and ballx < co[2] and bally+ballvy > co[1] and bally+ballvy < co[3]):
     crash=1
     ballvy*=(-1)
    if(crash == 1):
     w.coords(block,-10,-10,-20,-20)
  if( (bally > 248 and bally < 250) and (ballx > playerx and ballx < playerx + 60)):
   ballvy*=-1
  if(bally > 406):
   ballvy = ballvx = 0.1
   ballx = 200
   bally = 150
  ballx+=ballvx
  bally+=ballvy
  root.update_idletasks()
  root.update()
except Tkinter.TclError:
 pass
 

Note, I didn't include any kind of timer for this application, so if its slow/fast then increase/decrease ballvx and ballvy (or even better, write some code than handles timing :-)
