state.displ() is computed internally as state.pos - state.refPos, so the
displacement from the "original position".

state.refPos may be set manually to arbitrary value, you can try something
like b.state.refPos = b.state.pos. You can do this regularly to color the
particles according to "displacement increment" from previous color change.
This way is quite flexible, so depending on your needs you can use
different approaches.
