I would enjoy making a ray-tracing GPU from one of these.

That the cores don't run in lockstep can be shader heaven! I'm imagining using the cores in a pipeline with zoning so some core 'owns' some tile of the screen and does z-buffering, and other core does clipping of graphics primitives for each tile, and a sea of compute nodes between them chew up work and push it onwards.

Some kind of using the cores as a spatial index too. Passing rays to other cores as they propagate beyond the aabb belonging to a core.

Doubtless it wouldn't work like that. And wouldn't work well. But its fun thinking about it! :)
