FAT WIRING

Thinner cables would be possible by configuration.

Indeed. I was suggested that several times...

Right, this is a nice and useful application, the best I think for Arduino, that´s why aesthetic is also important.

Yes, this is already requested.
Requesting it again and again will not make it to be implemented faster.
By now this is very low priority because there are many critical things to implement before.

But let me comment a few things:
- Wire thickness depends on zoom factor.
- Wire thickness has nothing to do with more or less easy to handle.
- Aesthetics is something subjetive.

Ok, it is in your hands.

Now it is much better. Thank You very much.

Yes, I reduced the thickness a litte bit.
Note that the wires must be thick enough to see the color when animating.

Now is perfect, perfect.
