A Strange One: Sony Rolly
I see very little detail, but can only infer from this video that the Sony "Rolly" is a tiny device that responds to music and moves around. (I also presume its name rhymes with "Sony," even though it is spelled like it should be pronounced like "Raleigh.")
Yes, it's a flash, moving tube with no discernable purpose. Sony's still got it! [via Engadget]

It appears to have speakers on the ends, so I guess it's a DAP.
Er, I'm not sure what dialect you might be indulging in, but "Rolly" would be pronounced "Raleigh"? Rah-lee? Not Roe-lee? True, Polly would be Paw-lee, but Rolly just looks, you know, like the word Roll (like a tire does) with a Y.
Not criticizing, just curious.
Seems that the video might be fake after all:
