Take a look at my
"SplinMotion Tutorial". Also, to get the expanding telephone cord look, take a look at the "Helix" plug in which is available at the Maxons
"Plug in Cafe", or a commercial
'pro' version is available from the author. You might also consider Maxons
"Dynamics" plug-in which will make the 'hanging cord' process automatic. Or you might also want to take a look at Arndt's
"Dynamix" plug-in to automate the process as well.
