I love that video for some reason. When it came out I actually saved the FLV file from their website because my kids liked to watch it. Great marketing, IMHO.

EDIT: Here's the original video direct from their website (higher quality): https://www1.hitachigst.com/hdd/research/recording_head/pr/P...

This is cute. And because it's a flash vector animation and not a video, you can do a neat trick.. Zoom in on the page and it will scale up the animation smoothly. This clip is perfect quality at any resolution.
