Hi,
This reminds me of a snake lillyorchid took in called loopy.
the threads are to be found;
Here,
Here,
And here.
I know a lot of the pictures and video's no longer work but I did save one of the videos showing his looping behaviour.
The problem is it is a 4.4meg flv file - do you have anything that can play those or should I find you links (I use an older version of this ) or convert it into another format?
Other formats are likely to make it larger as I am not exactly a whizz with these things.
Let me know what you want to do.
**edit**
I should point out that while loopy definately has the wobbles he is not a spider.
