Hi Andy,

>Any hints??

Create an image of the frame, rods, & reckoning bar with the rest of 
the image transparent.
Group that image with buttons or images for the beads.
Script the group so draggging a bead is contstrained to the axis of 
the rod, bar, & frame, also moves the beads above/below it 
appropriatey, and displays a running total.

You should be able to place the group over any background and see the 
background in the space not occupied by the beads, rods, reckoning 
bar and frame.
