Rainbow Lightcasters
Rainbow Lightcasters should be
suspended as you would a mobile, 6 to 36
inches back from the window to one side
or the other. Lightcasters also work with
artificial light so they can be suspended
anywhere in the home, but a sunny
window area is an excellent spot.  They
work by reflecting the light, not by light
passing through the piece. By suspending
them any small air current will cause the
piece to turn which will automatically give
it the correct angle no matter what
direction your direct light comes from.
Fishing line works well for hanging.  
Experimentation with your Lightcaster
may  bring you unexpected happy results
