I'm poking around Nokia trying to decide between an N70 or N80, but that's not the point.
I called up the Nokia main portal page, then moved my attention over to something else for a moment, and in so doing inadvertently moved my mouse... over the "Business Solutions" button... twice.
Two notes rang out. "ding" "dong"
hmmmm
Further ludic exploration reveals that the two green "Business Solutions" and "Culture of Mobility" buttons have the playful characteristic whereby sequential notes of a melody are played on individual mouse-overs.
Neat. I played with it for a while. I suspect I know who inspired this.
