When its working it uses the video sensing to have you move your hands to guide the spider up the dry spout.
working on it - got the rain to fall when the clock runs down! - working on the way the spider is washed down by the spout ( havent figured how how to have the spider ride the wave of water rushing down yet) - finally got to use the backpack! I recycled my rain and cloud sprite from a Purplerain remix project The rain is blue in this case
