In my version of bounce.py, Box is lowercase:

from visual import *

floor = box(length=4, height=0.5, width=4, color=color.blue)

ball = sphere(pos=(0,4,0), color=color.red)
ball.velocity = vector(0,-1,0)

dt = 0.01
while 1:
    rate(100)
    ball.pos = ball.pos + ball.velocity*dt
    if ball.y < 1:
        ball.velocity.y = -ball.velocity.y
    else:
        ball.velocity.y = ball.velocity.y - 9.8*dt

There is not Box I don't think:

>>> from visual import Box
Traceback (most recent call last):
  File "<pyshell#0>", line 1
    from visual import Box
ImportError: cannot import name Box
