[Cuis] Cuis on Raspberry Pi

[Casey Ransberger]

Also consider that the graphics hardware on the Pi is very nice, and can't
be compared with much of anything about the Alto at all. GPUs are much
better at some computational tasks than CPUs are, which is something not
mentioned above. So it's *more* than a thousand times more go go go.
