#Cork-Screw animation
Holger:
That is an easy effect to create! Just render the entire cork-screw
animation in wire-frame first, then use it as an background. Now
create your box and give it a matt attribute and animate it wherever
you want to see the background. Now render the entire animation
again in phong, with the wire frame version as your background, and
wherever the matt object is located you will see through it to the
background!
