A wriggly worm thing 
A few settings available, so you can set your own colour or use the auto cycle.
A preset colour is set as an example.

Sync to PC for best result.

Plenty more to come, its just finding the time to do it.

[Jim]

I like it very much, and the variations are cool too

Jim

[bikemadness]

Wow. You could title this: 'A spider trying to find an anchor point in the wind'

[Xone]

Thx for the comments 

The coiling aspect of the path is part of the research I'm doing to try and understand how electrical arcs
can be coded between a positive and negative charge. Maybe in future I'll figure it out and post
the results in yabasic.
I'm sure it can be done quite easily with a turbulenced sine wave, but i'm trying a different approach 

[Shockwave]

Are you planning to make an accurate representation or do you just want it to look good?

Beziers are really nice for making electrical patterns that arc around.

[Xone]

The plan was to make it look and move realisticly, but unlike this worm thing, I'll
be trying to cause the path to jump from X number of points.
I'd like it to be entirely unpredictable in the way it emits, arcs/loops and finally connects.

So I'll have a critical energy charge applied to the points, and when they reach critical charge
level, the paths will jump from the two nearest charge points and be released at the point of contact.
Taking a fair bit of thinking about
