Notecard animation day 2

The rest of day one i dealt with solving the problem of keeping my background image of the staircase the same in all the notecards.  The way i solved this problem is by drawing out my image on one notecard, and on that card i poked holes wherever there were corners.  Then all i had to do from there is line up my notecards and color in the holes i poked to mark where my lines should go.  This method has worked out for me well, but for the last scene my background is more complex so i am waiting to see if it will work for that.  i began to draw the ball bouncing down, and i am incorporating the distance it must change from each card, using the information i learned earlier about a ball bouncing down a staircase.  i have markings on the top of my notecards to make sure i am not positioning the ball wrong
