[Cuis] Cuis on Raspberry Pi

Hannes,
Quiet interesting and impressive. Seems Marcus was comparing the Alto to
Rpi model A.
Now with model B we get 512 MB RAM and a 700MHz ARM that can be soft
overcloked up to 1GHz without voiding the guarantee.
One thing to note is that the Alto was bi-level (b&W) whereas the RPi is
capable of up to 32bits and openGL 2.0 or 2.1 I don't recall.
I will try Juan's suggestions today and will let you know.
Best
Nacho
