I'm curious the status of pmpd2d and pmpd3d as I do not see them in Pd-extended 0.43.4. I'm also wondering if there is something I haven't found yet to create results using pmpd2d to mimic things like iLine2D. I see examples like 58_pmpd2d_sand.pd (also not included in Pd-extended 0.43.4) which is close to iLine2D but doesn't seem offer the flexibility of parameters. For example, using pmpd2d how would I create a "squishy" line for my masses to react to such that they appear to reacting to a repulsing magnetic force as opposed to a hard wall?
