Light balls: juggling, toys, etc.

This idea just popped into my mind and I thought it wouldn't be that complicated to make, maybe even in time for christmas! I was thinking about juggling balls that would light up upon movement, except I don't know how to make them. I don't know how big/heavy motion sensors are, but couple them with leds and a battery, stick everything inside a plastic ball and presto.. or am I simplifying too much?.. Better than that would be to use the power generated by the movement to light up the leds, somewhat similar to Powerballs, but that I have no clue as how to do.. So, any ideas on how to make them?

You can make simple motion sensors with a wire and a spring

how, exactly? i don't think i've ever seen that before..
The wire goes through the spring
(That's what's in the blinkybug I linked to)
Not exactly. Similar principle, but a little different (needs a harder impact)

You could build something like a Blinkybug, but without the legs, and inside a ball.
