t=Tk()
t.config(bg=colours[randit(0,7)],width=randit(0,200),height=randit(0,500))
t1=Tk()
t1.config(bg=colours[randit(0,7)],width=randit(0,200),height=randit(0,500))
t2=Tk()
t2.config(bg=colours[randit(0,7)],width=randit(0,200),height=randit(0,500))
t3=Tk()
t3.config(bg=colours[randit(0,7)],width=randit(0,200),height=randit(0,500))
t4=Tk()
t4.config(bg=colours[randit(0,7)],width=randit(0,200),height=randit(0,500))
t5=Tk()
t5.config(bg=colours[randit(0,7)],width=randit(0,200),height=randit(0,500))
t6=Tk()
