Nokia has been pretty quiet of late, but the company has been steadily engaging in some low-key marketing via its Nokia Conversations blog. As you might expect, much of the content is about the cool stuff Nokia is doing. Describing such activities can be a challenge, but Nokia has risen to the occasion with this clever five-minute video on the topic of Cognitive Radio, a project under way from the Nokia Research Center in Finalnd. I had no idea what Cognitive Radio was before, but now I have a pretty clear idea thanks to the animated segment about Basil's search for his dog, Pepper, which combines twee Brit narration and a style that seems like a mashup of Pixar and Davey and Goliath. In a category where advertising usually revolves around gadget fetishization, this is a fresh approach.
