Nice if we can move bones like this:

P.D: May be some coder can extract the actionscript to take a look

## Inspiration (about armature constraints)

It's not that hard for a programmer to implement, apply IKA on selected joint truwout the chain. (Also called spline IK)

**d**.

So if point

**P1**moves, you have to ensure that

**P2**stays a constant distance

**d**. So you calculate a line

**P1**-

**P2**, and place

**P2**on the line where the distance is

**d**. For the remainder of the chain, solve for

**P2**to

**P3**,

**P3**to

**P4**, and so on.

Moving a link in the middle of the chain is similar - for

**P4**, you solve for

**P3**-

**P4**and

**P4**-

**P5**, and so on.

What would make the problem more difficult is if the ends of the chains were constrained, or if it were in 3D.
