Cell simulator screenshot

Not-high-enough-res screenshot of a running Cell BE virtual machine. A bit of a drudge to use, but damned if I'm not giddy. It's basically like being ssh-ed in and X-forwarding from a very slow machine - pictured here actually *booting* Fedora Core 5.

Very neat, though it doesn't model penalties for memory access (which is, as far as I can tell, the biggest threat to Cell performance) and/or the actual PPU (Power-PC unit, the core of the machine), just the behavior of the SPUs (the eight floating-point, graphics-card-esque units attached to the PPU).
