in my attempts to blow Tyson out of the water on this challenge (

no offense, of course! hell, you KNOW i'm not going to! I'm just trying!!), I'm using that Rivendale Split Things Up script. Any ideas on how I can get those particle chunks to reassemble in their original form?
Not actually become the same mesh like they started, just fit together in the right places, like a puzzle. I'd like to use them as a particle group, so they'll just be particles. I've got a few ideas, but i'm not sure about any of them, and wanted to get some more input before I get started.
