converting PD patches to Max/msp patches

Mr. Banshee's icon

Is it possible to convert PD patches to Max/msp? If so, how does one go about it? i have come across a really cool controller built using a PD patch, that was done by Jaime Oliver

*i included a actual patch in an attachment in this post, but can also be grabbed off his website

i wanna do this patch in max. Any help is appreciated. Thanks!
