Different color lines

[Wavesonics]

In complex situations it can be hard to see whats pointing where:

I think randomly coloring the lines might be good, or how about coloring the lines base on what they are pointing too, so if two things are pointing to the same memory, they would have the same color.

Also maybe slightly offsetting the "attachment" point that arrows are pointing to so multiple arrows pointing to the same memory block? Not sure on that one.
