Windows Sounds Track

Mac Sounds Track

These were inspired by this very old Windows Sounds Flash animation that did the rounds back in early 2000.

These videos hit 3 touch points that help make a good viral.
1: Technology: people eat up content around technology and
2: Lots of work: any video that makes you think, "wholly shit that would have taken ages" gets good traction.
3: Music: Check the top viewed videos on Youtube and you'll see its heavily dominated by music. Followed by sex, obscure and the humor.
