"We decided on a length of 1.5m, plus a few dozens of centimeters wire free at the end. We made a few changes to method described in the tutorial, but it is a great and easy method to make tentacles."
Maybe I'm old fashioned, but where I grew up you didn't come into a man's house, admire his tentacles, and then build one three times larger. That's like rustling his cattle or leaving him gut-shot after a gunfight. It's just not done.
Just wait till I get my hands on some industrial cling wrap. Then you'll see what "escalation" is all about. Bwahahahahahahahahaha!
