looking for a LWP that looks like a secondary process

[aeneas shrike]

I'd like to find a LWP that would appear to someone unfamiliar with LWP's as a background activity. Kind of like the device is doing a secondary process while idle, like Sony's Folding At Home.

I'm supposing it could be a long loop of some kind of process progressing through stages. Perhaps like the swampwater lwp, but where the organisms evolve and change. Any ideas?
