OK I just saw some stuff about this in the archives (e.g. try 
[pmpd/pmpd2d]) but that didn't work and neither pmpd2d nor its associated help 
file appear anywhere on my drive. This is Pd-extended 
0.43.4 release on ubuntu 12.04 32 bit installed using these directions

I&#39;m also wondering if there is something I haven&#39;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&#39;t seem offer the flexibility of parameters. For example, using pmpd2d how would I create a &quot;squishy&quot; line for my masses to react to such that they appear to reacting to a repulsing magnetic force as opposed to a hard wall?
