I’ve been playing with animations and opacity to make one cable almost dissapear.

I’ve used my last interact experiment, it seems the most promising way to build the interface of cables project, so I added a second wire, and change the opacity. This is a really simple change, but I have to take in mind use prefixfree from Lea Verou, modernizer or some other library that clear the path with the prefixes hell.

Probably, my next steps will be add wires on demand (using a button or something) and make on hover effect to only see with full opacity the wire selected.
