This is a very common operation if you want to perform some animation like the one seen on example 6.
Thanks , but do you have maybe a high resolution animated.gif file , because at this size i can’t read the nodes setup .
Now it should be seen better.
Thanks for the example
Re-opened at OP request.
Although I´m an Animation Nodes advocate, the work done by The Mantissa (Midge Sinneave) has inspired me to do some examples just with modifiers.
